So occasionally I think I shift the vehicle from F to R or vice-versa and it doesn't "take". Sometimes it is associated with an alert sound (but I don't see any text) but most times it isn't. I'm pretty sure the speed in <3mph, although I'm thinking perhaps when I've heard the audible alert I was going a tad bit faster? The one scary incident was when I was trying to do a "quick u-turn" on a very narrow road with stop-and-go traffic. It took me 4 steps to complete the turn and on one of the steps I thought I had put it into forward and then I hit the accelerator and just about ran right into the curb behind me. I did some experimentation on my own and it works just fine when I'm watching, I can go into F while rolling backwards and vice versa, at speeds up to 3mph. Just interested to hear some theories on what I'm doing wrong. Perhaps I just don't push the stick far enough once in a while?
