>"So that's it for GM. BMW already went that way, VW, and Toyota is starting to sniff out the subscription markets too."
Nissan already does it. They all do it, at least on some services. And if there are any that don't, they will soon. Once you spend a TON on a new vehicle with fancy features, you are stuck. Especially with the driver assist stuff that actually does rely on continued map and other updates. I will grant those services probably should be paid services. However, you are a captive audience at that point, and it shouldn't cost owners several hundred dollars a year for something that really only costs the company a few dollars.
1) There can be no competition in that space. So there is zero market pressure to keep pricing reasonable.
2) Most consumers aren't going to know or shop those costs at vehicle purchase time, since they will be "free" for X years.
3) The pricing could and does change at any time. So even if you thought it might be $200/yr, that means nothing when 3 years later and it is then $400/yr.
4) You don't even have assurance the services will even be available X years into the future. At some point support is lost, regardless, and some of those fancy features will stop working.
And a final note about pricing. Once my Ariya ProPilot 2 included subscription runs out, I probably won't renew, which will revert me to ProPilot 1 functionality. Why? Because I only drive about 2,000 miles a year. The company charges the same rate to everyone, which means it has far, far, far less value for owners like me (because it costs far, far, far more per mile or per trip or per use). I image most of the companies do this flat-rate thing, and it will only seem "fair" to, at most, those driving/using the features the "average" amount or more.
