2 seaters can follow each other like train track cars in a train, or replace 4 seater or 6 seater, while allowing multiple drivers go their own way with a passenger and maybe some space, especially given most people drive alone with not much storage space being used most the time and b/c incresing need and want for both husband wife to go to work at different places at similar/same time plus grocery and other acitivty, software allow one car to follow another like traincar in train track, so 1 driver with 3 passenger, b/c both cars are powered,normal trailer driving style of slower braking and turning vs normal driving, is not needed…. all with computer programming. ridesharing is usually done for one customer at a time too given people move alone most the time.
effiency in running cost payoff such maybe its even less cost over ownership time vs buying minivan or 4 seater, maybe 4 seater and 2 seater replaces minivan, etc.2 cheap two seaters with a app to make one of them auto follow the other like a train. this allows husband wife to goto different places at same time which is unfortunately becoming more common b/c rising cost of living. maybe teh cars can be efficiency optimized for city (lighter weight and more compact but less aerodynamics) except there could be a removable and/or folding front end areo foil similar to what freight trucks use in teh space above truck roof, covering the trailer.
Have compact city car then have detachable areo like or front end of f1 car, etc. i dont think anyone is going to want a second car with increasing cost of living. people will probbably live in compact areas b/c cheap, so most shops etc are nearby given lot of population desnity per shop. so, low speed travel will increase. So compact car is grea.t for these conditions.https://www.youtube.com/c/NotJustBikeshttps://www.youtube.com/c/NotJustBikes
