pmd is a good evolution of personal transport.
the unfortunate thing that has happened is due to mis used by some. no consideration of other users etc.

now pmd is illegal on walk path. many start to use pma. now again the problem is not in using pma but in the dangerous used of pma. so don't over killed by easy way of cut off. cannot used.
better to have license requirements that will requires users to pass safety unerstanding and sharing of path road with other users safely. speed limit sure need actince and regular enforcement sure need. but don' band it.
what is your problem with a family of 4 on a pma if it does not cause danger to others?
