Okay, first off, let it be known that I had drunk the Tesla Kool-aid and proudly announced to anyone who would listen that my 2015 P90D was the real "ultimate driving machine" until this Monday. I told everyone that my Tesla was smarter, safer, quicker, and cheaper to operate than any ICE vehicle. My trouble began a couple of weeks ago, on the second day after installing 8.0. Similar to others, the radio function was irritating and had trouble getting signals, but not so terrible that I would suspect foul software. Los Angeles was experiencing very hot weather, and on the way to work, the main screen was rebooting every two minutes, so after about four of these episodes enduring the shutdown of the Climate system, I "soft-booted" using the two steering wheel push wheels. This seemed to fix the problem for the remaining hour of commute (LA, of course,) but I stopped by the Lexus service center and they indicated that I should do two more soft boots within the next 48 hours, which I dutifully did. The problem was seemingly solved, but on Monday morning, I drove down to meet my crews early in the morning with the normal issues regarding 8.0 detailed by others regarding the Autopilot and radio peeves, and for the only the second time in over a year of driving, it started the reboot issue. I again dutifully soft-booted, and met my crews, finished the meeting and entered the vehicle to head back to the office. The main screen came up, but the dash displayed a message that I should press the brake after it indicated the car was "On". Of course, after approximately four minutes of waiting, I realized that it was in "never-never land", so I soft-booted, but again it wouldn't start for another minute and then finally cleared. Now five minutes may not seem like a long time, but if your $130K car doesn't start for no apparent reason, it seems like an eternity. On the way back to work, I called the Service Center and inquired about my problem, and they indicated to me that Hurricane Matthew had taken down a server, and they had issues with most of the fleet with similar problems. It is now apparent to me that a natural disaster or malicious hacker can take out the entire fleet and there is virtually nothing we can do about it. I was also told that a software update addressing this issue would be sent out, hopefully, by the end of the week. I have also determined that the Internet reception sucks now, and I don't get any more than two bars on the LTE indication, no matter where I am. Why don't we have a manual override so we can have control of the car to use or turn off the drive function in this event? For myself, I am now skeptical that any time I get in the car, all of this wonderfulness will be taken away like a computer re-booting, or a smartphone with exploding batteries. After this experience, I just don't have the same feeling about a "smart car" and surrendering complete control to the HAL 9000. If a hacker takes over my vehicle and commands it to go 150 miles per hour, I don't even have a "kill" switch, and in the case of natural disaster and loss of the Internet, better get a scooter.
