Impressive Tech?

So, I saw this the other day while waiting at a set of traffic lights.

I was impressed because the sign seems to imply that the van is “restricted” to particular speeds in different areas.

Restricted to me means that the driver can NOT go above those speeds when on those types of roads. I just wonder how it works. I will grant you that the tech for this already exists and I’m not entirely sure why it isn’t compulsory.

You can fit a vehicle with a GPS receiver and a set of maps so it “knows” where it is. This is connected to the ECU and hey presto, you can’t go faster than the speed limit allows. It should be easy enough. There might be some issues with travelling on the motorway over a bridge and the GPS thinks you are suddenly in a 40 zone but this can be worked around I am sure. I am not sure why these aren’t the law.

Anyway, if the van uses impressive tech then that’s brilliant. If the tech is a biological ape then that’s shit.

I’ve asked Sky. When I get a response I’ll put it here!
