Yeah, I put my CRV's key in the first position from "lock." It's the one that I would use to listen to the radio without the whole dash lit up. That way my steering wheel remains free. BUT I have to make sure I turned the radio OFF (have had a dead battery.
)
Before you decide to tow a car, check Motorhome Magazine's
Dinghy Towing Guide to see if your car can be towed 4-down, 2-down, or only on a trailer. I had a Subaru Forester, and was very surprised (read: ticked!) to learn it cannot be towed with ANY wheels down. So I traded my beloved Subie in for my Honda CRV (a very popular 4-down toad).
Also, you cannot back a toad up (the steering wheel will rack one way or the other unless you are perfectly straight). However, that has been a problem for me exactly once, because I always make sure I can pull out of any place I pull into.
