Spotted this quite some time ago but keep on forgetting...
SMB5Y and SMB6U looks like they have the black box thingy to
track the driving behaviour of BCs...It is mounted near the
headlight switch there..
It seem to be a light indicator that has 4 components..
Speeding, Acceleration, Brake, Swerving (Clearly rmb the first 2
but not sure about the last 2)..
Is this related to the black box thingy that SMRT said?
