Re: Confused as a result of attending too many different driving classes - Need help
Hello,
Firstly I would like to congratulate you for your first car purchase and wish you happy miles of smiles.
Half-clutch driving uphill. I learnt first in a swift diesel dzire and the car used to roll uphill even in half-clutch first gear combo and the driver kept impressing on the need to use this technique for all cars uniformly. The second school I joined also did the same thing. The Maruti Driving School Instructor laughed at me and told me that this will not work for all vehicles and specifically will not work in Petrol vehicles at all and demonstrated the same using a Petrol Wagon R.
I think this is specific to clutch itself of that specific car. Not petrol or diesel. If I'm wrong, please correct me.
Some cars are have long clutch and you can smoothly control engine to wheels power but some have short clutch and they cause engine stall if we improperly synchronize the pedals.
Half-Clutch is used in uphill and heavy traffic but AFAIK using it regularly isn't good for engine/clutch life. Instead try to control by brake and when you feel engine is going to stall, use the clutch.
If your mind sticks with synchronizing of Clutch, Brake and Acc. then you don't even look at them. As well as gear timing. After becoming expert with one car, it just takes 10 mins to get used to on any other car.
For gradual stopping from high speed to crossing a hump, should we keep clutch depressed, brake first slowly, reduce speed and then when near the hump, shift to second gear? Or should we not use clutch use at all till we are about to change gears?
For sudden braking, irrespective of speed, should we brake first or press clutch first fully and then brake?
Here is what I do:
My car is going at speed of 60 KM/H and I'm on 5th gear. I see a hump in safe distance. First I apply the brake slightly and when speed starts to cross gear ratios, I depress clutch fully and downshift step by step. When I think the speed is fine to cross the hump, I keep that gear, engage the clutch and cross the hump (with acc. if needed). 2nd gear should be fine to cross most humps but if hump is high then I'ed choice 1st or 3rd if hump is tiny.
For sudden notice of hump, you'll have to use both clutch and brake. Indeed brake comes first but if speed goes below the gear range then you have to apply clutch otherwise engine goes off (You'll notice it though)
Like I said above, when your mind understands the engine power, clutch engaging, gear ratio then it just happens in your legs and hands but you'll only focus on road.
- Bumper to Bumper Traffic - Best way to move - Understanding synchronizing of Clutch, Brake and Acc. In a empty road, drive your car in 1st gear and then apply brake slightly. In a few moments you'll notice engine is about to stall and thats the time to apply clutch. Here you can practice the clutch and acc. combination.

- RPM is the indicator for Gear shifting or Speed? - In my driving experience, I haven't even looked this thing for a minute. Speedometer helps to choice gear but only for beginners. Once learnt, car speed is understood without looking at speedometer and you change gear at that speed. i.e writing a letter in computer without looking at keyboard. Just remember not to raise acc. too much and change the gear.

- Can we downshift from 5th to 3rd and 4th to 2nd? - Yes you can but don't shift to a gear when car speed is not it that range/ratio. i.e 2nd gear on 40 km/h or you will seriously damage the engine. Remember gear ratio given by Arijitb, you'll can also find that written in car manual, windshield, sunvisor
