I was hugging the left side of my lane to steer clear of a suspicious looking Civic doing about 45mph on the freeway. A car approached from my left, triggering ELDA and nearly sending my into a spin. Luckily my years of autocross training kicked in and I was able to counter-steer and maintain control of the vehicle.
Just kidding . The alarm went off and I held the steering wheel while the car tried to send me to the right. Really, now that I've associated the alarm sound with the need to firmly grab the steering wheel I don't find it all that obtrusive. I do agree that Tesla should have warned people about this new feature and should provide some data about how much it improves safety.
That's more or less the same scenario I my first encounter. Except the car on the right was a Semi, the overtaking car was a lifted Truck (F350 I think) and happened to me on the first day ELDA was rolled out, so wasn't aware/forewarned/prepared to have to fight the car
The alarm went off, I thought WTF, and whilst working out what was going on/reading the message the car was heading towards the center of the semi (between the cab and the wheels of the trailer, where the M3 doesn't see anything).
