I drive a BIG-ass Mercedes and recently went driving in both a Supra Mk III and a 1968 Mustang GT California Special, all of which have ridiculously long bonnets... In each case, I can't say it was a problem for me.
Conversely, a number of people have pulled out on me when I'm going round a roundabout and these are big, loud cars that you can see coming a fecking mile off. I also had someone side-swipe me in the company van on Wednesday, when they were right alongside and level with me. This thing is MASSIVE, so there's no way they couldn't see unless they were staring at their crotch... although given who I work for, it may have been an intentional attack.
So yeah, it's not the cars, it's the dumbfuck drivers not looking... but weirdly enough, I have far fewer problems of this nature while riding the bike. Maybe I'm just going too fast for the trouble to catch me!!
