Awas means 'Warning' in malay. If you see this car on the road here in Brunei you better slow down, as you will be passing the Brunei National Biking Team.
Nathan often waves at these guys when he's out on his bike. Apparently they are happy for anyone to join in their rides, but their times are not always suitable for Nathan, so he has only done it a few times.
I'm glad to see that they are taking this kind of precautions though, and has a proper follow-car to make them more visible in the traffic.
