I actually fielded such a design in one of Curt Lindmark's TSAR email games back then. It was a fight in a shopping mall parking when you had to park, disembark and *run* to the mall's entrance (in the middle of enemy fire...).
Because the rules for disembarking meant it takes a very long time (like TWO seconds!!), I elected to go for a 25K bike. Somehow I still have the writeup for it... The IBA bike rider (sans shell) would jump off fast once parked (with retroboosters...) and the sidecar "passenger" with driver controls would drive away.
The design was deemed legit. I had planned a second-by-second acceleration/booster scheme, and it did work as planned, and I withstood a TwL shot without going up in flames... I had time to stop and disembark at second 7, but that's it... Unfortunately, the game was aborted at that point (took a LONG time to play out by email).
