Well, it appears that Ford doesn't want you to
drag race the new Mustang. You void the warranty if you race it at a drag strip, but not if you do a solo run, if you're testing it.
I know people will say "Oh they've been doing this for years with other companies, myah", I still think it's ridiculous that they're doing this. Why do it if you expect a lot of your customers to drag race your brand new car? Why implement line locks if you don't want your customers racing their cars
legally?
