i 100% agree with you. However I don't think the drivetest centers would appreciate having to clean up vomit on a daily basis.
I know you were kind of joking but this is probably the reason why they don't do this...because someone's sensitivities might be hurt. I'd rather someone's sensitivities were hurt rather than me being hurt because some assclown thinks they are indestructible behind the wheel of their Mazda.
