All new cars must have the devices from 7 July, adding fuel economy as well as safety. Will mpg become the new mph?
In the highway code and the law courts, there is no doubt what those big numbers in red circles mean. As a quick trip up any urban street or motorway with no enforcement cameras makes clear though, many drivers still regard speed signs as an aspiration rather than a limit.
Technology that will be required across Europe from this weekend may change that culture, because from 7 July all new cars sold in the EU and in Northern Ireland must have a range of technical safety features fitted as standard. The most notable of these is intelligent speed assistance – or colloquially, a speed limiter.
The rest of the UK is theoretically free, as ministers once liked to put it, to make the most of its post-Brexit freedoms, but the integrated nature of car manufacturing means new vehicles here will also be telling their drivers to take their foot off the accelerator. Combining satnav maps with a forward camera to read the road signs, they will automatically sound an alarm if driven too fast for the zone they are in.
My car lets me set a threshold - currently +7mph. I can see on the dashboard when I’ve exceeded my self-imposed threshold, vs when I am between that and the actual speed limit. Actually I wish it would do a bit more, like turn yellow.
I also ignore it in crowded areas, and pedestrian crossings, school zones, construction zones with people working, etc.
Although I’m really pissed at whoever thought the wide straight parkway leading through the woods up to my workplace is 15 mph. That’s the reason people ignore speed limits
However it is not set by anyone but me, never limits the vehicle, doesn’t make noise, and doesn’t get reported to anyone (as far as I know).
