...a four lane road clogged with cars and constuction would be much MORE dangerous than a less traveled two laner, but of course your neck of the woods might be different.
I agree, on a four lane road, people tend to drive faster, there's more cars, and a more likelyhood of a pile up. More people die in car accidents every year than shootings and airplane crashes combined.. That's probably not making you feel better, but I also believe you are being over paranoid. <img src="/images/graemlins/wink.gif" alt="" />
