One of the instructors at the course i took said young women are the absolute worst when it comes to watching for bikes on the road. I work on a delivery truck and spend a lot of time on the roads and highways in the GTA and i couldn't disagree with him. On a daily basis i see girls in cars texting, putting on makeup, talking on the phone, playing with other things.. might sound unfair to single them out versus men or older drivers, but they do seem to be the least attentive and also seem to think that signals on their cars were not meant for them to use. Multiply that by 100 if they are driving beemers or other luxury cars. But that part goes for all drivers. Seems like the higher end the car, the less they feel they need to use signals.
