Interesting rig - I got to ride one at the Davis Rally a few years ago.
Was pretty much just like a trike, with a few exceptions.
Being used to a trike, I really had to be aware of the extra width on the chair side.
It
seems to turn differently if you are going right or left. On a trike the center of horizontal rotation is in line and close to your body. On the Tri-Car it seems the center of rotation was off to the right when turning right, and in line with the trike portion when turning left.
The air flow off the windshield caused a permanent breeze from the sidecar windshield on to my right side. Force of the wind depended on the speed.
I used to have a sidecar on the Harley - the same happened on that rig (How it turns, wider on one side and wind off the chairs' shield). Quickly got use to it all.
What did
not happen on the Tri-Car that happened on the hack was the pulling to the right when starting out, pushing to the left when braking, a "skidding" feeling around some corners, (doesn't on the Tri-Car due to both wheels being driven) and for the life of me I couldn't get the sidecar wheel off the ground.
On the Harley, If I gave it too much (or just enough
) right turn I could loft the chair wheel and even ride like that for a bit. The Tri-Car was too heavy over there for those kind of shenanigans.
Oh- and turning right you'll only bump over a curb once. (Don't ask me how I know.:blush
