"You'll get used to it in time"...means if you are any sort of a decent driver you will modify your Western training to be far more defensive and vigilant..learning to back off and let them go. By now you should have realised Thai drivers are aggressive and selfish, and as a result you have to adjust your driving style so as to avoid a collision. Alternatively, record their antics and take it to the RTP Traffic Division and report them. ????
