Past Doritos Spinner
In my old Corolla, I'd double clutch into 1st because I think that car has no synchro on 1st gear, so you'd grind it unless you are almost completely stopped(below 5km/h or 3mph). I think synchro on 1st gear has become pretty standard soon after that, though. I have driven a friend's 02 Civic Coupe 5-speed and downshifting into 1st didn't grind.Of course double-clutching isn't necessary on a modern car. That's what the transmission synchronizers are for, right?
Knowing that your manual transmission vehicle uses synchronizers, you may think there is no point in understanding how to double clutch. There are still specific scenarios, however, where it can be useful...
Like when you're slowing in stop-and-go traffic, and you need to engage 1st gear. Or when you're downshifting from 6th to 4th (or 3rd), for passing slow vehicles on a 2-lane highway.
When I pass someone on the highway, I just do it as quickly as possible, so I don't like double clutching as it slows you down.
Overall I think it's like left foot braking. If you can do it well then you can keep doing it, but it's not something I would recommend to anyone.
