4x4s are a status symbol for rich people to cope with the Ribena slick outside Waitrose, I doubt their proliferation is caused by speed bumps, although you're right in that they do fly over them. Bring on the cameras.
I have already explained how the cameras cannot possibly work because they will be needed in such great numbers as to be unaffordable.
Whereas shutting a road to motor vehicles is not only very cheap indeed, it reduces motor traffic speeds to 0mph, allows the landscaping of a much more pleasant vista, and doesn't require the imposition of profligate surveillance. Why would you rather have a 20mph pollution-choked speedbump-ridden rat-run than that?
