Cars can be used to ram people. But most people simply dont want to do that.

What is different about cars and new tech is that new tech comes with the ability to track and monitor all users. So historically we didnt mind if one in ten million people wanted to ram people with their truck on purpose. But now the power to monitor everyone all the time to prevent these "one in ten million" crimes exists.

Its up to you to decide if the trade off is worth it.
