Personally, I’m not against the idea that Sonic would ever go behind the wheel. I just think it’s more for using it in official rule terms like racing or driving in a street in town. I mean, his demeanor to run around everyone might set off the law makers in his world, no?
For regular Sonic, I gave him a hybrid model car of the Speed Star from Sega All-Stars Racing and the sequel All-Stars Racing Transformed.
For classic Sonic, I gave him none other than the rad red Cyclone from Sonic Drift. :)
As for Boom Sonic, he gets the go-kart he rode for Archie Comics’ Sonic Boom #6-7.
Also HATE HATE HATE drawing the cars, all of my hate!!! At least it’s not bad for a first try. :D
