Does Chevy have these kind of updates for the Volt? While I like the updates I can see where the way traditional manufacturers do it is better
Chevy does updates for the Volt via Dealer Service just like other manufacturers. No OTA updates. OnStar is the closest service that does get OTA updates (it has an app), but it is billed as a separate service with extra fees (after the initial "free" period)
A couple of Volt software updates have caused some issues with owners, one notable one that added automatically turning the car off after 1 hour (after someone left their Volt on in a garage and the engine fired up once the battery drained). Others were camping in their Volts, etc and using the feature safely and were very upset when GM removed it. They refused the update, and were able to do that since nothing else in the car changed or was internet connected
