One of their VNL 760s like this

The system installed on our units have a Lane Departure warning system as well as a proximity system for vehicles ahead.
If the truck is being driven with Cruise Control engaged, the unit will slow gently as it catches up to another vehicle, and it does so without warning, and it does so with a HUGE margin - too much, in my opinion, so that you might not notice for a while that instead of doing 67 or 68 (what ours are set at), youre doing 62.
It will set off an audible warning if you are approaching a slower vehicle at a faster closing speed than the device allows and again, if the cruise is set, the unit will apply the brakes.
If you are in traffic and using the accelerator pedal, the warning system never shuts up, pretty much. The vehicle in front of you has to be pulling away, or the god damned warning tone just keeps going and will drive you nuts!
If you are in traffic and using the cruise, the vehicle will just keep slowing down every time a car changes lanes in front of you. Its a pain in the ass, frankly.
I prefer to drive the truck myself, thankyouverymuch. I dont need a bunch of sensors and alarms telling me what I already know! But its the wave of the future, to be sure. Engineer the trucks for drivers that dont pay enough attention to what is going on around them, I suppose.
OK all you folks that think I need to have this in the trucks I drive, go ahead, pile on! Tell me why Im wrong for wanting to rip the fucking system out by the roots!
OH, and BTW, if you have a Radar detector and it keeps going off in the 24Mhz range, it is all the trucks and cars with similar systems doing that.
