I haven't bought for a long time, are these required to run the car? Or is it just prohibitively obscure to disable it (smash the antenna or connect it to ground, for example).

Probably not intended to be required, but some implementations are buggy. IIRC when 2g was killed off some Subarus had a problem where they'd keep trying and failing to connect to a 2G tower until the battery died
