Great discussion OP!
I would love to change:
1. Locate the power seat adjustment controls to the outboard bolster so you can at least glance at them upon entry.
2. The Front Axel Lift (FAL) control button may have been moved on later model year (MY) cars. It is on the Cruise Control/Speed Limit stalk on my '18 MY car. I usually accidentally activate the speed limiter before having to start over and trigger the FAL. Also, once this process is completed, I don't need the information screen to remain on the FAL completion notice until I push the FAL button again.
3. Better Key Fob Recognition technology.
4. Better Track Telemetry Interface. I have this option and have never been able to make it work. A paltry dealership network makes this education process more difficult, but maybe McLaren could upload some detailed videos on how to use this feature.
5. Bigger fuel filler piping. Kudos to anyone who can fill the fuel tank without a shut-off triggering!
6. Make the MSO paddle shifters standard on all cars. My hands would get fatigued if I hade to use the smaller shifters.
McLaren could focus on better electronics/electronics interface resolutions to improve its cars. Nonetheless, I absolutely love the driving position, visibility, power, handling, and tactile controls of my 720S. I hope they preserve the steering wheel for steering only and keep hydraulic-assisted steering!
