Ok one example is from Taman Kinrara Jalan TK 1/13 to Serdang Raya Jalan SR 3/3. It will ask me to use kesas no matter what. But the practical way is by Bukit Jalil Highway. When going opposite from above route it will also ask to exit to kesas highway and will never take the bukit jalil highway.
At start, it will use a funny route, instead of going right, it will ask me to go a big round by using left.

Then when about to reach destination it will ask me to make an illegal u-turn then turn left. But obviously I can turn right and reach my destination. This road cannot make U-turn but it ask me to do so..

When routing from Kota kemuning to Serdang it will never use the bukit jalil highway but ask me to travel to 2 tolls until seri petaling. But a better route is actually exit from Puchong via kesas and head towards bukit jalil highway.

Sorry if my explanation is bad. lol
