I disagree. Tactile barriers like curbs and even rumble strips provide real security because they are such effective signals to both sides. Pedestrians would be much more afraid if cars only had to stay in painted lines and people had to walk right beside them.

At this point it's no longer particularly newsworthy to write a car lost control and leveled three people on a bus stop. It happens all the time, it even happened on the bus stop I frequently used 20 years ago.

And bike lanes are already segregated with at least paint so that's already a signal. People just need to get used to it, which is hard initially when all you know is cars and walking.

Drivers intentionally cross plainted lines they are not supposed to cross all the time. Drivers rarely cross curbs intensionally.

SF for example is full of solid white lines. The law says solid white lines are supposed to be treated the same as concrete barriers. No crossing period. Yet people cross them all the time with impunity. If they were actually curbs people would only rarely cross them accidentally

It's easy to stay on the right side of a curb as a pedestrian, compared to looking for floor markings, traffic signs etc.

As a cyclist, it's easy and essential to stay on the right side. Accidentally not noticing the curb will result in a crash or near one.

Modern kerbs are sloped. Accidentally not noticing the kerb will not make you crash. (See the picture about ⅓ down on https://bicycledutch.wordpress.com/2016/02/23/goes-cycling-c...)

Research shows sloped or even leveled kerbs don’t seem to lead to problems (https://journals.open.tudelft.nl/ejtir/article/view/3254)
