What if, we can have faster than light travel. We can't realistically have ultralight anything, unless it's on rails.
To me it seems inevitable. A self driving AI so no accidents, then a minimal frame to keep the wind off, an chair to sit on, and a few tires. And the batteries are swapped as a service/variable cost like gas is today. Get where you need at 60 mph.
There is no way to build any 'minimal' frame for $1k with any material that's remotely lightweight. Heck, even the current battery technology is sort of low energy density. You get around 220Wh per kg (or 0.8MJ vs gasoline's 46MJ). A hundred kg would be 22kWh. With a lightweight body - 400kg (~900lbs) [price not withstanding], highly aerodynamic model on good asphalt - I'd say 250km (155miles in freedom units) is realistic - but then you need cooling system to charge them, unless you consider they can be hot-swapped (or willing to wait longer).
What you suggest is proper futuristic stuff taken from a sci-fi flick, none of it would happen anytime soon.

What exactly makes this case different?
