The tech in the RR is a deal breaker. Anyone who has used it will tell you it's a dinosaur compared to BMW. Slow response, slow screen transitions, clunky address entry, poor voice controls, lack of street-level traffic, etc. The cameras have a terrible graininess and resolution to them as well. In a $100k car it's just not acceptable.
See for yourself around 2:43 in. It's awful (and I don't want to hear anyone complaining about X6 cargo room when they see how the back seats in the range rover don't even come close to folding flat). Cooley thought the cameras were defective the resolution was so poor, but this is how they are. There are long threads on the RR forums about how poor the cameras are, and the speed of the tech - oy vey.
