Just took a trip from the Los Angeles area to the San Francisco area and had some random observations about the car, 2018 R, 7,100 miles on the ODO.
- Speedometer does not match 3 different GPS units and is LOW by about 3 MPH in the 70 MPH range. So I'm going faster than I think when cruise is set at 72 MPH. I've checked this in my previous cars and they all matched the GPS so I'm going to assume the GPS units (all Garmin) are accurate and the R is not. Not sure if there's a calibration setting somewhere.
- There was a thread about someone using ACC and it not working the way they wanted it to (something about feathering the gas pedal to overtake a car or temporarily adjusting the speed and the car not returning to the set speed) and I did not notice any behavior from the ACC than what I expected. I tried to trip it up by feathering it and bringing the speed down slowly after passing someone but the car always returned to the set speed for me. I could not get the car to go lower than the set speed no matter how I feathered the throttle.
- Lane Keep Assist has a flaw I did not like - testing it on a long open stretch I let it bounce back and forth for about 8 seconds or so when it finally decided I was not steering so it dinged and told me to take over steering. If I did NOT take over steering, LKA was no longer functional and would just let the car fly off the road. Instead of continuing to keep the car in the lane (the LKA indicator was still green showing it knows where the lane is), it decided I wasn't paying attention and I might as well be killed - if the driver doesn't care, why should the car? That seems wrong to me. The car should not disable this if it knows I'm not steering yet the car just continued sideways over the lane markers in which ever direction it was headed.
- Lack of fog lights is a fail. Up in the Bay Area it was foggy on the drive back south and they would have come in handy for that stretch. Again, previous cars had them and they always worked well.
- Off-Road indicator is accurate in terms of elevation as it registered 4,140 at the Tejon Pass sign which says 4,144ft. Don't know if that's GPS or database driven.
- Water and oil temps got to their maximum and stayed there the whole trip. No fluctuation I could see. 70 MPH was approximately at 2,100 RPM so the engine got a good heat soak at a consistent temp.
- Main headlights are aimed a bit low and only seem to range about 2 seconds in front of the car at about 60 MPH. Seems to be a bit short. High beams are amazing though.
- Mileage up was 27 and back was 29, both at a very constant speed of 70 MPH through the central California valley on the I-5. All flat with cruise control on and in Sport mode.
- Steering is very numb. The wheel produces little to no feedback and, while rock solid and responsive, just doesn't seem to transmit car motion of any kind to your hands.
- The seat, while comfortable, needs more lumbar travel (it's puffed up to maximum but I wanted a bit more) and the seat could use a bit more padding as it felt a bit flat after a while (I'm only 155 lbs.)
