"Great!"
I mean to say, I am not extremely impressed. Sure congrats (sincerely) on jumping 26 cars, and holding the "record". But for the video, style of jump and a few other things I am not impressed much. I can't say it is terrible, but impressing me would be doing this in a sense that at least seems physically possible and safe. You just died. There is no way the driver survived that.
Also eliminate all variables with the record. Cars lining up on a server is first of all something that needs to be coordinated well (nice job on that) and can go wrong. Second people could have more / less gap between cars. I did notice you had them bumper to bumper, but even then there are discrepancies with them.
My suggestion is using stacks of tires aligned to the LFS layout grid. place four white, then a blue. Then four white ... so on...
The primary turn-off for me though is the act of killing yourself/driver. I get it is not real-life and nobody got hurt, but it breaks the illusion and thus immersion from the simulation, at least for me. So if I was to do this, I'd also have the rule that the driver must land on four tires, no rolling and remain under control (to some degree) when landing. IE- being able to stop the car.
As well as the 'launch' crashing into a car and using the lag/physics to boost up is another immersion break.
Anyways, those are my two-cents and feelings. Not a bad job though, so congrats.
