I get that all the time. No worries, it is just a warning that you are too close to the car infront.
You could turn it off in safety settings if you find it triggering too much.
Happens to me quite often. I would stop at a stop sign and when I accelerate, the car doesn't move until 2-3 seconds later. It caught me by surprise when I tried slamming on the throttle and the power suddenly comes on to the point that it was dangerous.
