Guys.. you are somewhat wrong
Firs of all - 'dabbing' brake will *NOT* disengage clutch (only for that short period).
For clutch to be completely disengaged you have to keep brake pressed (lightly is enough, just so brake light is on).
Same goes for *handbrake*! While car is stationary, and handbrake is on (light on on
dashboard), clutch is again disengaged.
But, if car is moving faster than approx 8-10km/h, than applying brake/handbrake will *not* disengage clutch. Car has to be stationary.
