I'm turning left and need some space to do so. This driver can't be bothered to wait and decides to ignore my safety for the gain of a couple of seconds.

I check behind me at 3 seconds and traffic is far enough away. I indicate at 4 seconds and start the manoeuvre at 6 seconds. At this time I'd doing around 18-20mph* coming into a 30mph limit. So a car slowing behind me only needs to slow by ~10mph as they are about to enter the 30mph limit as well and shouldn't be doing much more than that. The car passes me at 10 seconds, despite having 4 seconds to slow by around 10mph.

I took a second look at the clip frame by frame, comparing it to the roadmarkings and check distances using the measuring tools on Google Maps Satellite View. That's how I spotted that this driver was doing upwards of 45mph whilst in the 30mph limit. So that's why the driver had to do such a poor manoeuvre, they were going far too fast. And 45mph was a low value. Taking my first position guess would have put it more like 55mph.

So, a speeding driver breaking Highway Code 124 (and backed up in law in the RTA) endangering live and limb around them very close to a town centre.

Minimally this is breaking "Highway code rule 163".
