Gets into trouble on Shabbat and gets along well on weekdays. What to do?

You can tell him to open a savings account. When the Temple is built, he will be obligated to pay a fat sin for desecrating the Sabbath. I said this by way of recommendation, since it is permissible to violate Shabbat for the sake of a sick person, and therefore there is no prohibition for a Jew to drive. But there is no prohibition for a Gentile to drive, and this is even better (the easy way first). As a general rule, Halacha does not determine facts. Halacha determines norms given the facts. Halacha cannot determine that a non-Jew cannot be trusted. This is a question of fact. It determines that if you do not trust him, you must act in this or that way, or tell you to carefully consider whether it is right to trust him. So if he actually trusts the Gentiles in the hospital, why wouldn’t he trust them when driving? On the contrary, in the hospital they can easily cause damage without anyone knowing. When driving, what’s the concern? That he’ll have a car accident? And especially when he himself is also sitting in the car. What kind of nonsense is this? Halacha also says not to get a haircut from a Gentile because he is suspected of stabbing you with a knife. I hope he checks his book and asks him for a conversion certificate or evidence that he is Jewish. By the way, at the beginning of the second chapter of AZ it says that it is also forbidden to go to a Gentile doctor, and he fails all his patients with this serious prohibition, and even endangers them. I hope he runs his hospital with more common sense, and that his rabbi gives other instructions in a more logical manner.
