One of my cars has lane departure warning (lane keep assist), lane assist (vehicles in lanes on your nearside / offisde), all surround view (front, rear and side cameras), self parking, front and rear cross traffic warning (if you're nudging out of a parking bay and a car is approaching, adaptive cruise control (will bring the vehicle to a complete stop under normal braking as required) - the front rear cameras are useful when parking (the rear is great whenreversing up to a trailer as you can see when the hitch is over the towball), but the only one I use on the move is the variable adaptive cruise control in say 50 mph speed limits in variable speed limit sections on the motorway. Rest are a gimmicky in my opinion - nice to have, but would I use most of them - no. Probably down to trust. But I like to drive my cars, so as long as I'm fit and able, I like to be in complete control of my car.
