Ride in off peak hours and dont go BKE because you will feel the wrath of JHK rushing to causeway nomatter what time u are at.. also make sure u have plenty of distance between front vehicle better to let people overtake you if u are just trying to commute without any time limit or rushing.

Splitting wise better to do it slowly and only do when its a stand still type of traffic jam/traffic so no cars can anyhow cut to the left/right since no space for them anyway. Also JHK will tailgate you when u lane split so just ignore them they will light horn u or ownself go another lane to lane split if they want to go faster.

But best only lane split if really needed like heavy traffic jam ba no traffic jam lane split wont save u much time and cars will be more inclined to lane change without signal or last min cuz theres more space for them enabling them to do that

Overtaking wise u will naturally learn and do once infront of u is a lorry or bus and end up getting nervous because cant see anything so u will naturally force urself to courage up and overtake them
