I started this at the beginning of the contest but got busy and never really had time to finish, then today I realized the contest is ending soon, so here is my unfinished GTO. Be sure to read the explanation at the bottom, it's the most important part.
In 2050 all new cars will operate in a similar way as the Maglev Trains, the cars will float above the road on a magnetic field, there will be electromagnetic guideways below the roads surface and the cars will be propelled along the roads by changing magnetic fields. This means the cars will have no motors, and will have a very small amount of moving parts, increasing reliability and of course completely eliminating emissions. Since the cars are floating above the roads surface there will be no friction, meaning cars can reach incredible speeds and because they are propelled along guideways you will be unable to loose control of your car. The government will be able to set speed limits for each road and the cars will not be able to go over that speed, unless you can bypass the limiter , which people will figure out how to do.
