Long Distance Driving gives me a thrill - a thrill of driving >700 kms a day. We might also have been one of the fastest ones to travel from Singapore to London - in 49 total days.
However, the speed of the overall trip has nothing to do with the driving speed on the highway. On the contrary, I am a defensive driver. I am typically in the 2nd lane, allowing the fast vehicles to simply overtake. In unknown conditions, my approach is typically is to stick to the speed limit always and keep to the average speed on the highway.
The main technique therefore, to master for long road trips is defensive driving.
The "wrong" side
Beyond that, driving a right hand vehicle on the "wrong side" took a bit of adjusting. >80% of our road trip was on the other side. It makes no difference on expressways or dual carriage ways, but one has to be that extra careful on roads without a divider, in cities and roundabouts. Having said that, it is not a big deal at all. It took me a couple of hours of high concentration drive to somewhat get used to it and in a couple of days, it started feeling very natural. I could then start relying on instincts yet again.
