It might also be that there are no subpar suppliers and components, in fact they might be industry leading ones; our 70k Jaguar got the same parts for ACC, LKAS (there is no Lane centring on 21MY) as all the top OEMs . Whoever is in charge of infotainment and general electronics at JLR should be encouraged to improve all the ADAS, infotainment and other electronic issues the JLR cars suffer from either via SOTA if possible, if not in the future model year releases.
Can't comment on your last statement because I don't know either the marketing manager nor the "electronics" manager
That being said infotainment on 21MY is the first time the car is seeing the PIVI system. Yeah, there are bugs (expected on first applications) but most of them already squashed in the latest SOTA release. Whatever will be outstanding i'm sure will be resolved in future SOTA campaigns.
Likewise, the ADAS system installed on 21MY is the latest and very nicely future proofed. I imagine this one can also be improved via SOTA in the future (hardware permitting).
Yes, the car does not park itself as the previous MY but I am happily giving up that feature for the new 360 camera and the clearsight rearview digital mirror
Yes, it does not have steering assist but I'm happy trading that with the automatic speed limiter
