If we’re assuming these vehicles are FULLY autonomous, a simple fix for this is to add a manual override that allows the driver to drive for themselves. Then the heist is basically as effective as it’d be today. (To be honest, I’d be surprised if such a feature isn’t required by law).

Though off-topic, the conversation of vehicle-feature-defect-related heists reminds me of Jaime Zapata, a US agent killed in Mexico after his SUV doors automatically unlocked when parked. (Though it’s unclear if locks would have made any difference in the outcome).
