If you never driven Tesla you do not know what a joy is to use the auto pilot in stop and go traffic. I see 2-3 accidents daily caused by your "alert" drivers rear ending cars. Your statement may be true for long haul rides, but I pretty sure the numbers will come ahead for the auto steerer for the normal commute.

  "neighborhood"? Who commutes across a neighborhood as the full extent of their commute? I suspect it's within a rounding error. Driving across a city, however, I definitely see this. Daily. And "accident" I expect to mean everything from a light tap rear-ending to a full fledged crash. People rear-end each other in my city every day. On my commute, I'll come across two a day. Wet days, a few more. The other five directions headed into the city I would expect to see similar statistics to my experience. Just listening to traffic radio, there's going to be at least five crashes around the city; almost always more. They don't report on fender benders.

    About six years ago, I would drive from San Mateo to Oakland at least twice a week, after work, to meet my then-girlfriend. So that's down 92, across the bridge, and up to Oakland. It's about 30 miles, all on freeway, and at that time of day all in heavy (though not all stop-and-go) traffic. I don't think I ever saw three separate rear-ends in a single drive. I can't say for certain that I ever saw two. I didn't drive it every day, but I probably did 100 such commutes. You sound either like you're massively exaggerating or live someplace with apocalyptic traffic.

      You drove 30 miles up 880 twice a week and never saw a rear-end accident? You should play the lottery. I don't know if I see three every day, but I do see one every week. This week's was some clown in the #2 lane, _staring_ down at his phone, rear-end into a stopped car at ~20 MPH. His car was completely totaled with one of the wheels spinning off to the shoulder. A few months ago I saw a guy, face-down in his phone, smash into an existing accident that was already surrounded by fire trucks. That was amazing.

        I didn't say I never saw a rear-end accident, I said I never saw three in a single commute and am not sure whether I saw two in a single commute. The guy I was replying to said that he saw at least 2 every commute, often more. (Edit: Actually, sorry, 2 every day, not every commute).

        How do you have the bandwidth to look at other drivers' postures while driving?

      Here are the traffic stats for Canada[0]. In 2015 there were 116,000 "personal injury collisions". That is ~300 injuries a day across Canada. The Greater Toronto Area has approx. 20% of Canada's population (~35M). If we assume that 300 injuries are evenly distributed across Canada, which seems unlikely due to how bad the driving conditions are on the 401 and DVP, there are ~60 injuries per day in the GTA of various severities. I don't think someone encountering ~3 per commute during rush hour is unreasonable.

  Just take any job that requires a significant highway commute, you'll see more than that. Whenever you get full speed traffic occasionally interrupted by traffic jams (from whatever cause, other accident, tolls, weather, low angle sunlight, construction, etc.), you'll get a higher incidence of rear-enders. Especially when the tail of the slow/stopped traffic is at a point just past a hill or curve. I got rear-ended myself some years ago in just such a situation, clear sky & dry road. The traffic ahead had slowed dramatically driving into a section where the bright, low winter sun was in everyone's eyes, we couldn't see that before the gentle bend & rise in the road, I saw the slowing traffic & had to brake hard, the person behind me braked late and hit me even though I'd tried to stretch my braking as much as possible to give her more room. There was another similar accident minutes later just behind us. This kind of rapid-slowing situation in tight-fast traffic will likely even get out of hand even for automated cars, unless there is car-to-car communication. This is because of the slight delay for each successive slowing car in the accordion-effect accumulates to the point where eventually the required reaction time decreases and required deceleration rate increases past the performance envelope. At that point, a crash is inevitable. With car-to-car communication and automation, the last car in the pack can start braking almost simultaneously with the first one and avoid this. So, no, it's not hyperbole, it's ordinary.

    rapid slowing is fairly common in 280. I find it safest to be on the left-most lane, where you can use shoulder to get you a safe stop. rapid slowing is one reason i'd probably get level-2 autonomous car.

    "I got rear-ended once in fine conditions" != "I pass 2-3 rear-ends on my commute every day"
    - toss1 9y ago
      I didn't say it was -- I opened by agreeing, then also provide my example, as a lead-in to the car-to-car communication point. And yes, when you have an urban highway commute of any distance, it is not unusual to see that many crashes. maybe not every day, but not far off, and enough that you cannot rely upon commute times, precisely because the crashes are so unpredictable. You might try actually reading other posts before replying with trivial inaccurate potshots. sheesh

  Yes, if you can stay out of Los Angeles, I highly recommend it. 2 is average for about a 60 mile drive during slightly off-rush. I suspect rush is higher. And certain areas just seem to attract idiots.
