Tesla Model S owner here. The software on iOS and car is several years ahead of the competition. It embarrasses luxury German automakers. It’s made with the user in mind, it is elegant, and it is innovative in many surprising ways.

For balance, there have been bugs - the linking of key fobs to driver profiles has always been glitchy, and Tesla’s decision to use an inadequate eMMC chip was shortsighted given the volume of data logging. This caused issues for a few owners when the chips started to degrade over time. But to Tesla’s credit they later offered a free chip upgrade to all owners, and even covered the costs of those (like me) who got a third party replacement.

I rate Tesla’s software engineering. I’ve had years of issue-free OTA updates and sheer pleasure from driving the car. And having access to the car via an API is cool too :-)
