These kinds of "sensation" vulnerabilities have been making great headlines every for the past 15 years. However, there is nothing new about this.
- Relay attacks are nothing new, and not unique to Tesla.
- Every contactless unlock technique is vulnerable to relay attacks.
- No amount of encryption prevents relay attacks.
- Short range/near field wireless standards (such as NFC) are also vulnerable, though requires close proximity of the attacker to the NFC token (phone/card/keyfob).
Even HN often falls victim to these kind of sensational headlines. No, we can't solve this. No, car manufacturers won't go back to physical keys. Yes, 99.9% of consumers really like keyless entry and don't care too much about the potential of theft. For most, that is what insurance is for.
