Not so much an "anti-motorist" thread.... I'm starting this one to find out what vehicle sets off your radar... causes you to brake, give it room... in general, is the one that you've found to be the most dangerous and most unpredictable to your bike commute.
I'll start---The one that continually scares me is the Lexus SUV. It's not just the insulation a driver may feel from street. It might be the size, blind spots, age and type of driver... it seems like I've had more close calls or near swipes from Lexus SUVs than any other vehicle.
My commute is Hollywood, West Hollywood, Beverly Hills and West LA. Everything from Prius to Hummers, from Mini to Navigators, from Smart to Lincoln Limos..... every day.
