No, it's not that simple.

You can get an estimate, but unless the car coming towards you is on a perfectly straight and level roads you will get a false reading.

Modern systems can measure the speed of a target to within 0.3MPH, older ones <2.2MPH usually at between 20 and 50Hz update frequency and better than 95% (on modern usually 99%) resolution consistency.

Whether at all useful for logging the speed of another vehicle in any kind of enforcement sense is another matter entirely.

It's not to do with the equipment, it's physics :D

You will always get a low reading while trying to measure the speed of something approaching your position at an angle (or on a curve). Because from your location they ARE only approaching at that speed.

You have 14 days to issue a NIP. Even for things like careless driving. so regardless of views, if the NIP is given 49 days later it isn't valid. It has to be delivered verbally or by letter within 14 days of the offence date.

What if a policeman told someone at the scene that they would be reporting them for speeding? e.g. maybe the OP was stopped by police at the time?

Thats a verbal NIP, so the 14 days does not apply. They have 6 months from that date to issue the FPN or start court proceedings.

That constitutes the verbal issuing of an NIP. The paper parts received through the post are by and large the result of remote cameras or reports to ascertain who the driver at the time was. If the police stopped him at the scene, then they already know who the driver is.

If in the scenario whereby a NIP is issued but to the incorrect person (the receiver of Notice identifies someone else as the driver) then the time limit isn't an issue provided that first NIP was issued within the 14 days since reported offence; happy to be put right if in mistaken though. The S172 has a 28 day period in which to comply or, as mentioned above, the registered keeper can be charged for failing to provide information. I think that equates to 6 points and up to £1000? So serious stuff really.

You'd be issued paperwork to support that. Then the paperwork which arrives in the post is no longer an NIP.

That's not correct. There are a number of circumstances in which case going outside of the 14 days is perfectly acceptable.

exactly check post 2.
they will find a way.

Please quote the relevant legislation that would allow a NIP to be issued 49 days after the alleged offence, assuming that everything the OP has told us regarding them being the RK, no recent changes to DVLA records (address, registration plate etc) that may have affected the police's ability to get the RK's details.

You will always get a low reading while trying to measure the speed of something approaching your position at an angle (or on a curve). Because from your location they ARE only approaching at that speed.

Modern implementations can use sensor fusion and radar tracking mode to get absolute velocity over multiple readings.

On the oncoming vehicle speed .. if model 3 auto-drive were to evolve, it would need to be able to overtake on a single carriageway windy road, otherwise you could be stuck behind Doris, forever.

What if someone just stuck a 20mph sign on their rear bumper? That could be a fun game :D

I dunno how it works but the speed limit system in my parent's newer VWs seems pretty good at detecting the current speed limit - not sure how much it depends on a database but it doesn't seem easily fooled and so far hasn't struggled when speed limits have changed recently, etc.

There was one instance where a temporary 30 limit was in effect due to roadworks and someone had thought it amusing to change the 30 to an 80 - not sure if it just rejected the 80 as an invalid speed sign but it still picked up it was a 30 instead of former 40 or 50 limit.

It probably knows there is no 80mph sign. But it can't rely on mapping data as temporary speed limits are used.
