Well done! I had personally had driven through BP a couple of times during my time as a motoring journalist conducting road tests, one time in a Peugeot 3008 and a CX-7.
My only criticism is that I feel that there isn't enough vegetation and track width variations. On the flip side, I feel this captures the feel of old colonial federal routes in general, something like Ulu Yam or Titi Kong.
I also thought it would be nice that the track ends at the giant tengkolok (a traditional headgear) replica at the end, maybe in a future update perhaps?
