It’s a lemon market, as a car buyer there are no outward telling features whether the keyless entry system is susceptible to repeater attacks (most new cars still are), whether just anyone briefly inside the car can register new keys, whether it uses strong crypto, or whether a couple grand buy you a master key that unlocks and puts into drive most cars of a brand (famously Kia/Hyundai to this day, who also have all of the other vulnerabilities). Car reviews don’t mention any of these things, even when they are definitely known and tested (rarely) by some third parties. Strangely, not even the OEMs who have secure systems use them for advertising.
