I use to drive super duty's, I would pull into an HP spot and because I wasn't able to open the door and start the assembly of my wheelchair fast enough I had people giving me a hard time assuming I was parking a truck that's three feet off the ground in a HP spot because I was lazy.
Things are not always what they seem.. Their tune changed drastically when the assembly of my wheelchair had begun.. Someone might have a heart condition, who knows.. Of course there is abuse of HP parking like everything else..
