Had an incident detection go off on my Edge 530 leaving my driveway this morning. I think some brake shudder on the wet rims set it off. Never gave me the option to cancel it either, just started blaring after a few seconds, sent it to my wife, freaked her out, I had to send her the "I'm okay" and then text her a few minutes later.
You would think the fact that I'm still moving and riding would be a sign I hadn't crashed, but maybe I paused for traffic at the bottom of the driveway long enough, I dunno.
There's apparently a public beta for 3.55 that's out right now, so I'm going to install that tonight and try it this weekend. Supposedly has fixes for incident detection and live track, two issues I've been having. And overall stability, which I've been getting phone disconnects a lot too.
