While commuting back home from office I saw a cyclist negotiate a small puddle of water when a query struck my head:
How to negotiate a deep/huge puddle of water/mud in an automatic (2 wheeler/4 wheeler)?
I'm sure we have seen this quite a lot of times. Few cities have seen worse during rains.
Now, in a geared vehicle the correct technique is to downshift to 1st gear (preferably) and keep the revs high enough so that the exhaust's back pressure doesn't let any water seep in and reach the engine. This applies for all geared vehicles. (This is done to prevent hydrolock - Hydrolock - Wikipedia, the free encyclopedia).
What is the case with automatics?
We have countless number of scooters/scooties/cars running on automatic transmission on our roads. One cannot the stomp onto the gas in these to build up revs since the vehicle would simply shoot forward!
How does one ensure that the water doesn't seep in via the exhaust or in short, how to build revs?
