well it would take at least 5 dudes with electric cattle prods & billy clubs to force me to buy one & theres a lot of other people just like me so nationwide you would need at least 250,000 storm troupers to make people buy them & another 100,000 thugs with brass knuckles to make people actually drive them, so that's ummm about 350,000 jobs right there.
good luck with that mandate thing.
