Wendy Carnegie, in her 1963 book 'Gipsy Doctor' writes about the heat during her trans-Asia trip:
During the day the heat was so intense that I often had to wrap a cloth round the steering-wheel of the car in order not to get my hands burnt, and on occasions the wind was so searing that it was necessary to shut the windows. Worst of all, sometimes I found it too hot to go on driving, yet too hot to make any effort to stop the car, a most ridiculous quandary to be in!
