Whatever you think of the idea, or the potential for random, incalculable failures of the technology like those we already see today (speed limit recognition right now is patchy at best, after all), that’s not what we want to talk about right now. There’s another issue centred around ‘sporty’ cars.Cars with a decent slug of power, say, from 200 ponies upwards, allow more freedom on the open road. They make overtaking easier, they make quick getaways from the traffic lights – useful where lanes merge soon afterwards – safer and they usually pack better brakes, grippier tyres and generally communicate better with drivers.On the other hand, breaking the speed limit in such cars can be an inevitability. Whether it’s in order to safely get past traffic moving at 10mph under the speed limit, or simply enjoying the car on a quiet country road, these things happen. To arbitrarily say that any and all instances of speeding are inherently unsafe isn’t true, and there’s precisely zero evidence to support any such sweeping statement.Speed limiters will club powerful cars over the head harder than it will hit ordinary biffabouts. A limiter will act as a leash, holding the car back and canning that sense of freedom that many people buy more powerful cars for. At that point, the question will arise: why bother buying one at all? People will be able to buy a stylish car with a basic engine for a lot less, if they’ll all do the same speeds.It’s very possible that this will cause a lot of headaches at Porsche, Aston Martin, Ferrari, McLaren, Lamborghini and anywhere else that power and/or freedom are integral parts of the image. Even the more attainable options like the Golf GTI, the Hyundai i30 N and the BMW M135i may suddenly become about as desirable as foot rot. What would you be paying the extra for, really?Instead, heads will turn to the classifieds, where dwell cars without the speed nannies. People who want performance will look to these older examples, built before 2022. New sales of interesting models could collapse as demand skyrockets for a selection of limiter-less cars that will only ever get smaller.
