Fellow enthusiasts.... we often come to these forums and discuss the features we don't have yet. This post makes me appreciate a feature we do have. What I am about to tell you is an accident averted because forward collision alert actually worked and saved what would have been my own driver error. This weekend en-route to the beach (about a 3 hour drive) was a mix of 65-70 mph driving, at times, and bumper to bumper traffic, at other times, and everything in between. This typically would have been a stressful drive, but auto-pilot is amazing as long as the driver is attentive. However, because of the nature of the drive, construction along the way, or other factors, sometimes I had auto-pilot engaged, and other times not. About half way through the trip, I encountered moderate stop and go traffic. Auto-pilot was not engaged and I was following a car in front of me at about 35 mph. There were about 5 - 7 car lengths between us. I reached over to grab something and took my eyes off the road for what would have, in my mind, been a split second, but in reality was probably 3 seconds - tough to know exactly. What I do know is that while my eyes were off the road, I heard the "BEEP BEEP BEEP BEEP BEEP" and quickly looked forward and saw the red brake lights of the car in front of me RAPIDLY approaching my 35 mph moving vehicle. The car in front was almost stopped at that point. I was able to brake hard and make a very rapid controlled emergency stop as my heart sank into my feet. Luckily the car behind me stopped on time as well. Crash averted. My wife said to me (as she was oblivious to what just happened) "I hate those various beeps and sounds your car makes" and I was just sitting at a stop with my jaw hung open with the knowledge that, absent those beeps, I likely would have hit that car. The fact she was oblivious to what happened shows my technical skill at executing an abrupt emergency stop It only takes one of those incidents to remind me that distracted driving is no joke. I consider it a strong warning to me that I better not take my eyes off the road again auto-pilot or not - not even for a split second. It really can happen that fast. The car in front must have started to brake the instant I lost eye contact with the road. So, thank you Tesla engineers because despite the rare false alarms I have received via the forward collision alert, this time is saved my ***. I took the time to post this in the hope that other can learn from my own close call. Be safe out there!!!
