It will rarely get to site on time.

And there would be many 'roll-back' damage events where slip roads have traffic jams. And they would be expensive to install and maintain. And serious criminals may often be able to drive around them (and if you used bollards or something to prevent drive-arounds, then the bollards would probably kill more than the spikes would save).

It's wrong because:

- Criminals would hack the system for hijacks
- Criminals would jam or disable the system routinely
- Vehicles would be stopped in dangerous places
- Wrong vehilces would be stopped frequently (think around cloned number plate)
- etc etc


aren't these already available (after market).

The solution to stopping in the wrong place would be to put something in to fry the ecu when speed reached zero. Not foolproof but better than stopping in heavy traffic with no warning (no brake lights, for example)

Yes, with Tracker type devices I think.

True, but if the problem is wrong way on a motorway at 90mph that's one hell of a cripple - you might as well not have bothered.

Remote stop


I'd like to see you remote stop my old Turbo diesel Passat. I had the alternator fail and battery go flat on one trip in that thing, it just kept on running. Mechanical fuel pumps for the win. Good job it was daytime though :)

I'm also fairly certain that this guy went that way deliberately. If it's common knowledge that the police wont follow then it's probably worth it. Either that or he'd been playing too much Grand Theft Auto. It's far easier to make progress on the wrong side of the road in that game as you never get caught out by bunching and the police cars tend to crash more often.

I'd vote PIT manouvre too, but it's far from infallible. A good enough driver can get out of it easilly enough. Maybe we should have US-style spike strips too, though I imagine the number of civil claims for the tyres of innocent vehicles would make this an unprofitable and therefore unwelcome idea. (And at over £100 a corner for my car, with a requirement to do all 4 at once, I'd be pretty annoyed if I encountered an unexpected spike strip that I couldn't avoid)
