Minor problem. There was a very heavy downpour in the Bay Area and some streets got flooded. I had to go through one and I was going probably 5 miles per hour. The water was probably a foot deep. No idea what happened but the car beeped once and went into neutral. I didn't see any error or anything. Did I press the gas and brake at the same time? Did the car get some water inside? I put it into drive again and it was fine. Weird huh?
