or, apply full brakes, apply full audible warning and swerve at the last possible moment, while calling the emergency services to put them on alert. But how common is your scenario ? I consider this a more critical failure : The Federal Motor Carrier Safety Administration suspects that as many as 28% of commercial truck drivers have sleep apnea. The Sleep Medicine Division surmised that nearly a 250,000, persons fall asleep while driving each day of the year. Nearly half of semi-truck drivers have admitted to actually ‘drifting off’ while driving a long-haul route. https://www.hg.org/article.asp?id=29866 https://www.hg.org/article.asp?id=29866

> But how common is your scenario ? Anecdotally, the 3 truckers i've known have complained about it. I now drive very carefully around trucks. Swerving at the last minute is a non-option because it means turning sharply, which jackknifes the truck. Turning while braking is worse because turning while either braking or accelerating compromises steering. You can try to brake until the last moment and then take off the brakes and try to turn, but again possible jackknife, the wheels could have locked up to the brakes, and now that you're traveling slower you will actually turn slower, so it's harder to cut the wheel and go around. All of this within a few seconds. You have to either try to slow down and blow the horn, or get out of the way and blow the horn. Some people are lucky and either swerve away from the truck at the last moment, or their car only gets marginally crunched. One hacker friend of mine's car actually got thrown nearly into the opposite lane of traffic on the highway with the same scenario. Recovery took a while. I think he's still got pain and limited mobility.

  I don't doubt the cut-ins but I mean, how common is the disaster part? Not as often as truckers having incidents through tiredness etc. I'd warrant. > You can try to brake .... We're talking about "The computer ...."

  Of course, being automated allows for much more advanced braking schemes.

  I haven't seen a jackknifed lorry in a very long time, I thought that had been solved with anti-lock brakes.

For this reason alone I would trust autonomic trucks much more than human driven counterpart. I must admit, I've drifted away few times as well while driving passenger car over long, boring highways..
