From your tone I can tell you're not listening, but the car coop in my city has clean well maintained cars that are all less than 5 years old. The car share app has a fleet of prius v's that are in even nicer shape than the coop's cars.
But how often would you need a vehicle that goes +40mph to take your kids somewhere? It'd only be useful for drives where you'll be outside of the city for long enough to make the lower speed matter - since for city driving the limit is almost always traffic and stoplights not your vehicle's top speed.
Op was being an asshole but not wanting to share cars with the population at large is a thing whether it’s “a dirty hippie coop”, a regular rental car, or the backseat of a Lyft.
