One of our trackday group recently took out insurance for a day at Thruxton in his M3P and paid £194 on a £50k valuation with £2,850 excess through Moris.
When I compared time derived off a video vs the actual times for a lap I found considerable differences. - please don't ask me why or how, its just what I found.
But the why or how is what makes all the difference. A lap of what? What was used to time the 'actual lap'? Where did you time the lap from/to on the video? All of this has a bearing on how accurate the timing is. At a hill climb the timing is done with a flag stuck on the front of the car crossing a light beam at the start and finish. That's not the same method as lap timing on a circuit or using video or GPS-based data logging, but they can all be accurate to a fraction of a second when done right.
I think I agree with you.But the why or how is what makes all the difference. A lap of what? What was used to time the 'actual lap'? Where did you time the lap from/to on the video?

It's a shame you don't want to take your Tesla on track. They make great track cars.
. I think the best I'll get to do is to rent a caterham.
Video will be accurate down to whatever frame rate you use (often 1/30th of a second) but then it's up to you to pick the correct start frame and end frame and depending on where the camera is positioned in the car you may not be able to match where the transponder or timing beam is triggering it. To have a variation of more than 1/2 a second would be unusual. I developed one of the first computerised lap timing systems and several GPS-based lap timing solutions and my company specialised in onboard camera systems long before GoPro existed so I've got quite a bit of experience to draw on with all of this.I think I agree with you.
When circuit racing there is a transmitter on the car and its detected when you pass a fixed point, controlled by the circuit - this is very accurate. I have done sprints, which have a beam you break using a flat surface screwed to the front of the car, I presume there is similar on a hill climb and I have used GPS timing equipment with pre-set break points, which is also very accurate to the proper setup and utterly hopeless if not setup right.
When I have used video (on sprints and on track), I have found wide variation between the time I record on the video using video equipment and the tracks own timing equipment. As have others, however your results may vary, especially as the equipment we used is now massively out of date (Im talking early go pro's etc).
Oh I absolutely want to take my Tesla on track, but the lease won't let me
BTW, how to do the batteries last on trackdays and can you get enough energy into them from charging at the circuit? If I recall correctly there are commando sockets in the pit lanes, are they used? or do you use the 3 pin sockets.
There really aren't any deals to be had like that as an organiser. Any insurance broker will assess risk on a case by case basis and the amount of business they might get from a few people on a track day just isn't enough of an incentive.
You'd have to drive at such a slow pace you'd be black flagged!I'm curious how fast a lap you could do with 1 pedal driving - no brakes
Glad you made it and had fun! We had a great mix of EVs on this first UK EV track day. Plenty of Teslas but we wanted to be inclusive and welcome our other EV friends and I think we got the balance just right.I did a few cool-down laps with mostly no brakes, track mode on, it gets you the most aggressive regen function, pretty good.
The track day was great
