I was a bit surprised too... I did a fair amount of research, but there are some tablestakes items that many people would simply not think to ask about. For example, my last car was a 2012 Hyundai Genesis with their top-tier Technology package. It did not have Bluetooth audio streaming. That feature was on every other trim level of the car and every other car I knew about at that time. I figured it out after I had the car for a few days, because it never occurred to me that it would not have it. I put Tesla's missing cross traffic in this same category.
Cross traffic alerting is a tablestakes feature on every other remotely comparable car on the market today that I am aware of. It simply never crossed my mind that the Model Y, with its recent update, would not have that feature. I was aware that other tablestakes features like head-up display, SiriusXM, and CarPlay were missing, but with all their focus on advanced cameras, cross traffic seemed like a no-brainer.
I love the car, but there are a lot of little things missing that put the MY many years behind its counterparts in the market. This is my wish list, but I have 0 expectation I would see any of these as updates to my car:
- 3D camera views. Tesla is the only car I know missing this. Seems like it would be a no-brainer with their emphasis on Tesla Vision. Even its core rear view is worse than about every other car available today. Hyundai's, for example, is freakin' awesome. The lack of this feature makes the Tesla way harder to park in tight spots than about every other car on the market.
- Better lane changing UX on the basic autopilot. The basic autopilot lane changing is clumsy at best. Every other car in this class either automatically changes lanes with the turn signal or at least does not disengage and allows the driver to manually change lanes with the blinker while staying engaged.
- Cross traffic warning. I do not know of a car made today missing this.
- SiriusXM. The MY and M3 are two of a very tiny handful of cars in all of cardom missing SXM.
- Head-up display. Ditto, the My & M3 are among a very tiny class of cars without this feature.
- CarPlay/Android Auto. Tesla is the only manufacturer I know without CP/AA. On its best day, Tesla's navigation is a distant forth place in the world behind Google, Waze, and Apple Maps. (And Apple Maps is pretty mediocre compared to the top two.) At least it is better than almost every other car's built-in nav, but all those cars have CarPlay.
- Cooled seats. I was pretty surprised to discover that the Tesla lacks this. It is only luxury car I know without.
- Better blind spot alerting. Tesla has it, but it is the worst in the market. It's situational awareness and response is relatively ineffective.
The list of other missing, comparative tablestakes features is probably longer than above. It is reasonable that most people buying their first Tesla would miss a few and be a bit surprised and disappointed.
