You pick the car you want, with the accessories you want, and negotiate a price.
Lots of competition, most of the time. The last year has been weird because of chip shortages.
No prices fixed by the government.
You get to choose the dealer you wish to deal with.
Tesla has no dealers, and sells direct from the manufacturer.
Tesla is special in many ways.
In certain forms, they are not a car company. They are a technology company. Use the same loophole Uber and Lyft use to have otherwise illegal taxis driven by morons.
Tesla circumvents a LOT of laws that auto manufacturers have to comply with. Greasing politician hands allows that to happen.
Elon Musk got the majority of his money from Obama, played the Solar panel alternative-fuel subsidy game and then went on to apply his technique in every aspect of his fields.
This guy drills below ground with relative impunity. He has a space program which is illegal by international law, and is dropping implants into animals with NO legal ability to do so. But he is creative in the law and puts a ton of money in the hands of the same politicians who claim to hate him.
Elon Musk is proof that everything is a goddam act.
