I'm hoping for manufacturers to pull back on the "all controls are via touchscreen" and "you can't have carplay because we want to charge you our own monthly fees" trends.

Taking Chevy for example, they have physical HVAC controls, but they're counting on the average consumer being too clueless to realize they only have Google Maps in their car because it came with a free OnStar trial. Eventually people are going to notice that they spent $1000+ to buy the larger screen upgrade, and now Chevy wants them to shell out $300/year forever to be able to use it for maps.

The other big unknown is lifespan of car software platforms, if these end up being like phones where they get laggier and laggier with continued software updates, until eventually it's unusable, people aren't going to be happy about it. But we won't know for 15 years exactly how bad that problem is.
