I think these warning letters are a bit biased. I got many parking offenses and I'm driving a Perodua Kelisa. So far I have not received any warning letter from them and that web which you can visit to check, they displayed the status "Surat Amaran sedang dihantar" for months already.

This is in contrast with my dad's Sonata. Holy cow, within 3 days the warning letter arrived and keep bugger until final warning. Eventually, dad paid for it.

So therefore, I have these doubt as if they care for people who drive "inferior cars" and chasing over people who drives luxury or near luxury class cars.
