I remember reading about why driving on the right came about, but I'm wondering if there was ever any significant push to shift things over. I vaguely recall reading that our natural instinct to avoid a head-on collision is to break to the left rather than the right. Which is a problem in a car when breaking left puts you into the opposing lane. So given that (assuming I remember right I guess), it made me wonder why we didn't switch over, as it seems like it might make more sense.
Also, was/is there any movement to have the UK switch to driving on the right side of the road? I know that some countries have made a switch, so the UK possibly could too.
From Made in America by Bill Bryson:
"An unusual feature of Conestoga wagons was that they were built with their brakes and "lazy boards"--a kind of extendable running board--on the left-hand side. If there was a reason for putting them there, it has since been forgotten. With drivers effectively compelled to sit on the left, they tended to drive on the right so that they had an unimpeded view of the road, which is why, it appears, Americans abandoned the long-standing British custom of driving on the left."
I've never heard of any movement to switch back. the Conestoga wagon was very popular. It became quicky part of society, and at the perfect time--highways were expanding and gaining popularity.
