Assisted driving notes

For a company that offers ‘Full Selfdriving’ and ‘Autopilot’, you would expect it to have adaptive cruise control with lane following licked. Not quite. First things first, the adaptive cruise control itself works well. Adjusting the speed with a scroll wheel is very easy, it anticipates fairly well and it is confident and smooth in speeding up and slowing down.

However, the Autopilot lane following is unusable: it insists on being absolutely centred in the lane, and if you tweak it with the steering, it disengages. Make a lane change too quickly or too slowly and it disengages. Lane keeping assistance can be permanently turned off but generally works fine.

Our test car had the optional Enhanced Autopilot, which supposedly can make lane changes, take motorway exits and merge onto the motorway. Don’t bother

– it’s hopeless. It has terrible lane discipline, it dithers, it slows down to a crawl on ramps and it has a phobia of traffic cones.
