I don't understand how this stand-up trike would be of any benefit to police... If it only moves at 25mph they can't exactly use it on the road, which only leaves the sidewalks, and it looks a bit too wide for that to be practical as well. If they're looking for something for a single officer to patrol on, why wouldn't they just buy some little Suzuki GZ250's? They could pick themselves a few up for less than $3k a unit, use them for every day patrols, and if they ever needed to, they could still keep up in a chase, at least until more units show up.
I can't see this being good for anything , not even at Mardi Gras.
