Welcome to Just Commodores, a site specifically designed for all people who share the same passion as yourself.
You openly admit to speeding in the first place, but its more that your driving too fast for the conditions. Residential street with parked cars on both sides of the road, oncoming vehicles and driving a large vehicle yourself.
Shame the video's don't have telemetry on them (RPM, braking, speed, gear, distance to car in front) that would end a lot of debates. It would show exactly what TVR is doing, until then it's his word and everyone's assumptions.
One thing I've learned over the years is you can only worry about yourself on the road, some people are aggressive dicks on the roads and some people are petrified of the road and we're all human and errors of judgement account for a lot of stuff too.
I cant speak for whichever brand of camera TVR records with, but the one I am using gives you the option of removing or retaining those details ( and the sound ), when exporting the video.
The only thing I cant do is remove only part of the data.. ie I cant leave the speed displayed and remove the GPS figures, I can keep all of the data or none. Since the original video is retained until deleted, it means I could make as many different versions as I like, with data, without data, with sound, without sound.
Of course, if it displays evidence that doesn't support your case, you would probably leave that bit out when exporting
