I live in the country sourrounded by highways so the only place I have to ride are four lane roads with speed limits of 60 +. I ride on the shoulder and as I get to town the shoulder is gone, so if I want to ride, I don't have a choice.
People should just be more alert and careful when driving.
This is so sad!! To think that someone hit them even with a Van following with a big caution sign says to me that someone was really not paying attention at all, or asleep.
