only Lotus' buggy implementation of the auto-hold is stopping me from treating it like a handbrake, because I can't turn it off with the brake switch while it's automatically holding. but I can wait the full two seconds and have it release.
the issue isn't a lack of user options to avoid rollback; I'm very confident that I won't roll back. the issue is that their imperfect implementation can cause sudden confusion and concern to a new owner while in traffic.
I still haven't been back to the dealer for a software update, but the car now seems like it might be 'learning' a bit and I have felt the hold releasing before the two seconds as I start to let out the clutch. so maybe there was a bad initialized value or two in the program that took a few driving events to wash out?
