They can, but both of those are often encrypted such that it is at least hard. TPMS isn't encrypted so it is easy to figure out what cars are going by.
Encryption wouldn't solve anything anyway. The problem is not the content of the messages, that's just tire pressure, which changes constantly, and wouldn't be useful. The problem is the unique identifier that's being broadcast constantly. Theoretically its a very simple fix: Just implement a sort of rolling code that periodically modifies the identifier.
