It's not tough if you don't consider the administrative burden of checking all your criteria for everyone that wants a vanity tag. Some people build from plans, some build their own designs. Some companies reserve when contracts are signed. How does one easily, quickly, and cheaply verify that these qualify for n-number reservations? Who's going to bear the cost of the additional administrative burden? The reality of it is that if a plan is implemented so curb squatters it will also exclude some legitimate users in the process, it will increase cost and inefficiency, and some squatters will likely find a way around it.
Nauga,
all for a vanity tag
