Further, more injuries occur to cyclists on sidewalks than on roads. The sidewalk is narrow, so you have less escape route. Cars do not expect you on the sidewalk, so exit parking lots and driveways into you. Pedestrians, kids playing, and other hazards also appear without warning. Sidewalks are usually poorly maintained providing even more hazards.
And I'm familiar with the hazards of being on the sidewalk. Dallas isn't a place where people walk - I can count on one hand the number of pedestrians I see. When I approach some sort of intersection-like area where a car could be, I make sure a car isn't approaching, etc., etc.
I literally bike like everyone is out to kill me.
The nuances of how to do this well depend on rules of the road for your state, but it generally works very well.
No matter what you feel, the data shows that you're estimates and approach to safety in this case are just plain wrong.
In 2001 I was biking Market Street to downtown SFO. Agro Biker, several hundred feet in front of me, was heading straight through a green light. That didn't stop Stupid SUV from rushing to turn right, nearly causing Agro Biker to t-bone.
In response Agro calmly reached into his messenger bag, pulled out what I can only describe as a smoke grenade, and lobbed it at Stupid SUV's rear window. Direct hit. Shock and awe filled the streets!
The last thing you want to do is be a nuisance, all it takes is one unhinged, rageaholic to end your life for a very stupid reason.
I can't make a scene or get in the middle of the lane when I'm dead. And at best, I'd be affecting a few drivers a day by yelling at them. Maybe I'd educate some of them. The rest would just conclude that bicyclists are assholes, and every dead one is a net benefit.
Like I said in a different comment, I'll take my paranoid safety now instead of a possible payoff later.
And I ride in Trivandrum, a city in South India with aggressive drivers who get mad when they have to slow down and get caught in the really intense sun, minus air-con. (I've noticed a lot of middle-class folk here save on fuel by skipping air conditioning in city snarls)
Never ride on pavements.
Never ride on the edge/shoulder especially in India where a 'shoulder slip' could easily leave you with a broken neck.
Never ride near the dividing line.
Ride in the 1/3 of the road that lets you spot and recover from surprises served up by pedestrians AND Learn cross-steering if you ride fast on a road bike.
Being visible and noticed early-on is the key to survival.
Being 'in their face' is an effective way to stay alive.
However, I don't really know the driver's perspective.
There was also a guy who experimented with wearing a bicycle helmet finding that drivers would leave less distance when overtaking him when he wore the helmet. Apparently they assumed he was a more skilled cyclist because of the helmet.
Bicycles are vehicles. Sidewalks are not a place for vehicles. It's not fair to pedestrians or yourself. Also if anything were to happen while you were riding on the sidewalk I believe it would be you that would be at fault.
Also, I live in Dallas - we don't really have sidewalk traffic. Every time I ride my bike, I can count on one hand the number of people I see pedesting.
Also, someone else lives in Dallas. Every time he drives his car, he can count on one hand the number of people he sees cycling. He uses that fact to justify driving in a manner menacing to cyclists.
I'd also add that in many cases, riding on the sidewalk is illegal. It doesn't bother me when I see little kids doing it, but if you're a grownup you should be riding on the street, with traffic, in accordance with traffic law.
When I still lived in a small rural "micropolitan" area before moving to Akron a few years back, I was a road rider and belonged to a local bike club. There is no way they would have tolerated members riding on the sidewalk, and they stressed heavily that bikes are legally regarded as vehicles and have to obey the same rules.
I've since given it up, since I live in a high traffic suburb of Akron and being deaf, can't hear oncoming traffic. This wasn't a big deal on rural back roads, but now that there's a lot more traffic around me, it makes me nervous.Some states do have laws about what constitutes legally riding a bike on a sidewalk. For example, Oregon requires bicyclists to yield to pedestrians, and to generally go slowly, slowing down to walking speed when crossing a crosswalk or driveway: https://www.oregonlaws.org/ors/814.410
Common practice seems to vary a lot by area. Riding a bike on the sidewalk in SF would be unsafe, unnecessary, and against city law, but in suburban and rural areas with high-speed-limit roads (~50-55 mph) without bike lanes or paved shoulders, but which do have sidewalks, it's quite unusual for people to ride in the road. In suburban Houston, for example, I would be really surprised to see a bike in the traffic lanes on something like Texas Hwy-3, but it's not that uncommon to see bikes on the sidewalk.
The only exceptions to a person riding on the sidewalk is if the road does not have approved bicycle lanes, or the person is in a group with special permits, or the road is physically unfit for travel. As of the last 4 years, every paved road, with the exceptions of interstates, were approved for bicycle travel, even if they do not have designated bicycle lanes.

Granted, one may argue that any road is unfit for bicycle travel if the speed limit is 55 MPH or so, but you must prove in court how the entire road is unfit, which requires just as much effort as the DOT requires to gain permission to re-pave the surface from a graded dirt base.
What type of injuries though? And is this in any way biased by the fact the young or inexperienced riders are more likely to be using the sidewalk. On the sidewalk you'd expect inexperienced riders who do not cover much distance to be having a lot of small scale accidents. On the road you'd expect experienced riders who cover a lot of distance to be having fewer accidents (per mile, hour, rider?) but are significantly more serious on average.
I'd personally want to see more evidence before overriding my natural instincts that many busy roads are often just not worth it. As much as I admire those 'road warriors' who are educating drivers this is one of those situations where I have to put me first.
However. If it's night time, and i'm riding up a busy 45mph street with no bike lane, you bet your ass i'm riding the sidewalk. I'll be paranoid and stop at every single vehicle or pedestrian crossing, but i'll ride the sidewalk. I know the kinds of people that drive these streets, and I know it only takes one asshole veering 12 inches into the side of the road to send me flying at a pole and potentially back into traffic.
Drunk drivers, drivers on cellphones, people not watching the road, people looking for loose change in the glove box, or just freak accidents. Any single event could kill you on a bike. Where I live we don't have the luxury of taking up a whole lane of traffic to bike safely - if you do, the least you get is harassed (horns, trash thrown at you, threats). If they're driving an expensive car you're more likely to get run out of the lane because they know they own all the lanes.
One thing I have not seen mentioned is that cyclists are effectively INVISIBLE to cars when on sidewalks due to their speed. I work on a college campus and have watched motorists tune out sidewalk cyclists on a number of occasions - they aren't tracking objects moving faster than a pedestrian. On two of those occasions, the cyclists were hit - one was taken away in an ambulance with head injuries. Any near collision I've had has involved a pedestrian walkway of some sort.
As a cyclist your highest priority is to be seen. It's much harder to ignore a cyclist riding in the road.
