I am sure most people who do not live in India would never have the courage to drive in India. You will use a driver. However, what I am writing applies to both, those who drive themselves while on road trips, and those who use drivers.
I am referring to a recent road trip of mine, where I drove 1650 km into Central India.
Driving in India is not easy, and a 1650 km drive in India could be the equivalent of a 5000 km drive in Europe
We have cows on the highway
We have potholes
We have people who jay-walk on the highway
We also have narrow roads where the local tractor drives you off
We do have bridges that are under construction
Of course, amidst all this, we have some of the most beautiful country you can find.
The driving during this trip was hard, and so was the photography. However, I was driving alone, and the one thing that i realised was, that to make it back safe, healthy and with lots of good photos, what I needed every night, was a good night's sleep.
Apart from the tea breaks at the local highway dhabas, managing my sleep and rest was critical. This is especially so, since I was also photographing the places wherever I went.
If you use a driver, make sure he gets enough rest, and that he gets to bed on time.
Go easy on the alcohol as well. It helps to enjoy the trip!
