Actually, I would prefer the barriers (like we have in London) rather than being constantly harassed by inspectors. I have occasionally forgotten my ticket, or forgotten to buy a new one and then been caught... with barriers I would have no way of accidentally travelling without a valid ticket/card!
Kindly define "constantly" and "harassed". Asking for your ticket is not harassment, neither is fining you for not having one, no matter what your excuse is. Constantly, in my books, is on just about every trip. Does this really happen to you?
How would barriers work with the many different tickets offered on the
MVV system?
EDIT: Thank STB, that was a good start.
