Carsharing can be recommended only by somebody who never have to share a car.
- Car won't available when you need it.
- You will come to a car, which will have steering wheel and driver's seat in a setup incompatible with your physique, so you need to waste your time to set it back. Every. Damn. Time.
- Car will be dirty. All the time. Dog hair, food crumbs, trash (i.e. coffee cups, cans). You will take it out and next time it will be back
- If you are sharing with a smoker, I hope that you like smoky smell of your car.
- Car will be always empty (gas, battery) because previous user has no incentive to fill it up.
- Minor accidents will go unreported, and then you will be wondering, where this scratch came from, why is this mirror busted or why I need to hold my steering wheel 10 degrees to the left to drive straight.
- Everybody will try to evade maintenance fees - You want money for winter tires? I don't drive in winter man... 2 weeks later your co-owner will want to drive, because it is his car too!
Carsharing is a dead end and whoever will try it, will quickly revert back to his own car. Less headache.
