Part of The Villages lore mentions that the use of golf carts originated with drunks who had lost their driving privileges due to DUI's...so then decided to get around in carts.
Given that TV has certainly grown since then, it would be silly to think that we don't have folks who still fit that situation.
As to arbitrary stops/checkpoints, that subject can be looked upon from several angles and I don't see a 'one size fits all' answer.
While I don't want to be sharing the road with someone who is not insured or is impaired (for any reason), I also believe that a hard look should be given the number of folks who are physically not capable of driving safely due to age and/or other medical issues.
I see (and dodge) way too many people driving around TV, that in my opinion, should have had their licenses revoked a long time ago.
Maybe it's past time to require driving tests for those over a certain age?
I'm not sure what the ultimate answer is, but before one group/demographic gets singled out for being the problem...I think all factors should be taken into account.
