Even if Toyota drivers somehow drive slower than others, does that make them worse than the asshole in his BMW M3 who goes 80km/h through a school zone, or the guy in the Mini Cooper who nearly hits two of my co-workers as he zips through my workplace's parking lot in order to quickly beat someone to the last parking stall? Or how about the lady in her Audi wagon who is backing into a parking stall, and yammering on her cellphone, only to be scared $h!less when she backs right into a lamp post?
Idiocy on the road is not limited by brand.
Plus, saying Toyota drivers suck is kinda like saying my mom sucks, because she drives a Toyota, and I take issue with that.
