Larger vehicles than yours always have right of way.
More expensive vehicles than yours always have right of way. Note that this is calculated as at the time of purchase. Thus a 20-year old BMW still has right of way over your Honda, though it might be worth less on the open market.
Anything behind you doesn’t exist anymore. The person who just put their nose ahead of you can now pull into your lane, without signalling.
If you leave safe stopping distance between you and the next car in front, someone will immediately slip into that gap.
There are only two speeds to drive at, too fast, and too slow.
When it rains, speed up. Everyone knows that radar doesn’t work in the rain, so no need to worry about speeding tickets.
If you break down, put your warning triangle at least 500m behind your car. Very important people on busy schedules drive in the right-hand (VIP) lane at very high speeds. They may be too busy with important phone calls etc. to notice your pathetic little car stopped in the VIP lane. Put your triangle out, get off the freeway and wait for the breakdown truck from the other side of the barrier. Hope that it arrives before the next VIP.
It’s normal for people to drive alongside you on otherwise empty stretches of freeway. They think it’s safer to travel in groups, two or three abreast.
Many Taiwanese cars feature an autopilot system and do not require driver input. It’s normal to see the driver’s head in profile, microphone to lips, enjoying a karaoke session or watching a movie. Please don’t honk your horn as it makes it difficult to keep up with the subtitles.
