A Flaw In The Safety

Following on from the post a while back about driver assistance things, I had another interesting one a few days ago.

I’d hired a Vauxhall Insignia in order to ferry people around a bit, and the weather was disgusting – heavy rain, lots of spray, and lots of idiots with no lights on.

Anyway, on the section of the M4 I was driving on, there were roadworks, and the lanes had been narrowed as a result. And that was where the problem came in.

The Insignia had the Lane Change Warning thing, which detects when the driver is drifting across lanes without indicating – and in the case of the Insignia, it also tries to push you back into the lane you’re departing. Not my favourite thing at the best of times, but in this case it was actually picking up on the wrong lane markings (because they were glossy and shiny in the rain) and so actually kept on pushing me “back” towards the crash barriers, and would have left me scraping along them if I’d not been paying attention.

I can understand why it happened, and how. It was also easy enough for me to sort things out (eventually by turning off the Lane Change completely) but I can also easily see how things could’ve gone wrong, if I were the sort of driver who relied on these aids, who didn’t pay attention, or left those aids to do things because they’re there to help.

And what would’ve happened in that situation if it were a fully autonomous (“self-driving”) vehicle with no controls, or potentially people who didn’t drive, or couldn’t understand the danger signs?

There’s still a way to go on these things, I think…
