I find the cruise control useful. It helps me keep to the speed limits in town, and stops me having to monitor the speedo all the time on motorways. I use it a lot, particularly since the new 308 hybrid doesn't give a strong sensation of speed.
I have noted
before that I can't seem to turn off the automatic braking system when cruise control is engaged - they seem to come on together even if I have used the option to switch it off. I should note that this isn't the ABS anti-skid system that we have known and loved for some decades now - it's a system that is intended to slow you down if you get too near the car in front. Useful on motorways, perhaps, or for drivers asleep at the wheel.
So I'm trolling along in a built-up area, 30kph cruise control on, since that's the speed limit. There's a line of cars parked to my right. (I'm driving on the right; I'm in France). An impatient driver comes up behind and sits a short distance off my rear bumper. I'm thinking "If I braked hard now, he'd go right in to the back of me". At this point, the road bears hard left, and the car "sees" the parked cars as now being in front of me instead of to my right, and..... slams on the brakes. No car should do this. There was no need, the situation was risky, and no human would have taken that action.
The quick reflexes of the guy behind saved us from a collision, but he isn't happy. He blasts the horn, overtakes with a squeal of tyres and blasts the horn again. Can't say I blame him, and he probably thinks I did it on purpose. Of course any accident would be blamed on him: he was following too close. But I don't need the hassle. My car would be off the road during bodywork repairs, there's the hassle of organising that, and the insurance, and, last but not least, I'm having to explain to an angry frog that I didn't brake on purpose and that the car did it when no human would have done.
I went into the Peugeot garage to complain about this "feature". It's the sort of thing that could, I imagine, be sorted with a simple software fix. The guy wasn't optimistic. But I will update this post if I should get such a software change. In the mean time, I would probably get into terrible trouble if I told you never to buy a car with this feature, so I won't do that. But I'm beginning to think that had I known about it, I wouldn't have bought this car.
