This is going to boost the bike and sneakers sales... at least until the in-bike and in-sneakers ads. :D
Will someone destroy the audio system in their car, to avoid it so that you can substitute your own?
I would think that the ads and other features are going to waste power and that you should save power.
If the day comes that I can no longer avoid cars with user-hostile systems such as (but not limited to) "infotainment" ones, this is exactly what I'd do. Rip that shit out and replace it with something that suits my needs.
