- Staying with a manual trans.... I'm assuming yr question refers to coming
- to a dead stop at (say) an intersection. Clutch in, shift back thru
- neutral, and then pushing the gear lever into 1st. You then sit with the
- gearbox in 1st, the engine running, and the clutch pedal depressed until
- yr ready to move off again.
-
- For what it's worth, this technique might not be desirable:
- 1.
- The clutch release bearing is taking all the strain for the duration -- as
- is the clutch cable and clutch-plate springs. (Maybe this is no big deal,
- but why do it anyway? -- especially if you want to keep the car for a while.)
- 2.
- If yr backed up in traffic or waiting for pedestrians to cross (etc),
- consider the possibility of (a) yr foot slipping off the clutch or (b) some
- fella running into the back of yr car and yr foot going off the clutch
- (again). In either case there is a risk that yr car could jump forwards
- just at a time when you could least afford it.
-
- Don't want to sound like an old granny but I reckon the best technique is:
- 1.
- Stop and gear into neutral, foot off clutch. Handbrake on. Footbrake on.
- 2.
- To move off -- clutch in, into 1st, handbrake off, footbrake off etc.
-
- Like everything on matters of detailed driving technique there's no real
- "one size fits all" solution -- what's above is just what works for me and
- the way I figured it out driving British-made cars down the years.
- Cheers,
