I've experienced KSRTC ACC been driven in Cruise mode in Bangalore-Chennai day service. That's when KSRTC b9r were introduced, The driver was saying in cruise control we dont need to touch anything the bus goes automatically.=============
This is called overconfidence, waiting for disaster to happen. Never ever lift your hands off steering wheel while driving. One of the reason for accident is overconfidence [apart from overspeeding and over loading].
