So the current strat for killing Leo the Chef is to jump off the PCJ just as you approach him to run him over, this shortens the cutscene that is normally longer if you don't kill him immediately. But if you jump off the bike slightly before you'd normally do, the cutscene will not even start. I think this saves about 2 secs or so. The disadvantage of this is that it's harder to get the right angle to make the bike run him over if you're further away.

I'm sure if you have a good amont of speed and go in sort of a straight line you'll be able to get him further away

I never went for this because the time loss is more worth it than missing him completely on a godly cop car start imo.
