However you drive in UK, when in Malaysia just do things much more slowly, especially changing lanes.
And just because no on else seems to use the indicator, they think it wastes battery power, always make sure you do even if when wanting to overtake it seems that it makes the cars behind you speed up to close the gap you intend to move into.
As said above motorbikes are the biggest problem.

Just on the horn aspect, not sure whether driving is different in West Malaysia compared with KK but here it is advisable to keep off the horn and only use it to warn people of your presence if you think they have not spotted you, and let drivers cut in from both sides if necessary. In UK the horn is often used to 'tick off' another driver. It is not used for that purpose here in KK. Patience, and keeping your eyes peeled - 360 degree vision would be helpful. I have a LTSVP and needed that to obtain a Malaysian driving licence. The KK office had to send all the paperwork to KL to get approval to issue me a licence here in KK. My main motivation for getting a Malaysian DL was that if I had a prang, I was concerned the insurance may not pay out if I did not have one. This may be an unwarranted concern but I was not prepared to take the risk.
