The next paragraph is interesting too:

"Its range will be limited by 10%, and several features will be disabled via software (including our onboard music streaming service, navigation with live traffic visualization, and heated seats). Similar to other software-limited vehicles produced in the past, Standard customers will have the option to upgrade to a Standard Plus at any time. Similarly, anyone who has already bought Standard Plus and wants to convert to Standard is welcome to do so, and we will provide a refund for the difference in cost."

It's pretty confident to offer both upgrade and downgrade options between the two.

The downgrade offer is only for those who had already ordered. Not that you can downgrade at any time. It makes sense to offer this as your choice might have been influenced by the "permanency" of the decision.

Software disabled heated seats?

When the "switch" is on a display, software can do anything.
