My local limo transport friends told me this:
Don't take SG to JB private transport, when caught, the passengers will be implicated as witness.
Each of them individually questioned and compared to driver's police statements.
Don't side with driver and lie, just be honest and you (SGreans) will not be criminalized, you will be only be a witness.
They will invite you to Msia courts as witnesses, they are after Malaysian drivers.
Last week, 20 cars was stopped at Msia customs, another 14 after the toll gates.
During random-time raids, they will stop almost every Starex and Alphard with MY car plates.
When Anwar took over, anti-corruption is one major concern, now all Msian civil servants on their toes, kopi money now can't settle things like before.
Also, buying insurance will not cover accidents involving illegal car transports.
Pity those JB towkays, buy a fleet of big cars after border opening and now kena this.
