The main problem is the effective lane width is reduced. A much better idea would be to maintain or even increase lane width to allow for a larger margin of error.
Most of these are fitted to existing roads? Increasing lane width would
1 increase the distance pedestrians have to cross
2 decrease the size of the ped island
Kind of defeats their purpose?
I’ve found the larger lane widths are the ones where I’ve had most ‘dodgy’ passes.
On narrower, busy roads, I’ve found by taking the lane early I’ve fewer problems. The only one I’ve had a couple of times has been the sudden screech and smell of burning rubber as a late passing idiot realises their current speed and direction is going to take them onto the island, through the bollard....
