It's a waste to not give the best software possible to the car. In a car, a higher price is only natural if the car is more expensive to produce or develop.
They're not actually limiting the software (except maybe the music I guess? but that's no different then just shutting off your siriusxm trial). They're just limiting the hardware that wasn't paid for via software.
Are they able to completely cut off the battery by 10% or just the range? If the latter, wouldn't this increase the battery long term life similar to the extra unallocated space on some SSDs (i.e. Intel)?
People here would probably have no problem with the music trial, because that's clearly a service being provided, and not the hardware that you've "bought" and ostensibly own.
