I lived in Houston about 10 years ago. No disrespect, but I can't imagine driving a 3 wheeler around that town. With all the pickups and supersized SUVs on the roads, you are certainly a brave man to go against the grain.
Nothing to offer to your question...but just want to say congrats!
I live in the Dallas/ Fort Worth area. The prospect of encountering trucks in a M3W don't phase me. Just drive under them and continue on your merry way.
I too may have to look you up when next in Houston. I have yet to see one in the wild here in DFW.
