Passive parking assistance

On a sunny day I noticed along the freeway, a collection of short bump strips. It is designed to wake up sleeping drivers.

However I think that these tiny bump strips can be used to assist drivers in car park as well as in the freeways.

Essentially for every car parking spot, there is a single mini bump that tells drivers they are nearly hitting the curb.

To illustrate this here it is in text form

Car park:

C=---------------------- <-Car park divider

U=||||<---car move here

R=||||<--- & Roll over the "|" Which are bumps

B=----------------------

==||||<--

C=||||<--

U=----------------------

R=||||------ More car here

B=||||

==-----------------------

As the car move dangerously near the curb, the bump increase in height and power.

Also an option is to place these bumps along the car park border, to keep Idiots from straying to other car park places. Thus preventing others from using that same spot.

Thanks for reading, what do you think. Please comment so I can improve on this idea.
