A barrier curb, if it is at all possible for them to be aroused, they absolutely will be, and if that means they need a new front tire or rim on their car, well, I'd rather that than my child needing a new father.
More thumbs up than I have available to give.
A barrier curb will not absolutely prevent a vehicle from making an incursion onto the sidewalk, but nobody will deliberately cross a barrier curb at any significant speed, and even a complete drunk will notice if they accidentally cross it.
That is also why pedestrian refuge islands should have substantial concrete bollards at either end to protect pedestrians on the islands. Of course, it would make sense to design the bollards to deflect rather than stop outright a motor vehicle, but the priority has to be on keeping vehicles off the island.
