Either you missed the part about “if you can safely make it” or you dont care and are simply looking to take a swipe at “frum yeshivos”.
Typically, adults are ones who drive carpools, not kids. Similarly adults are the ones who drive the school bus. If you trust their judgement when heading out to shul or some other place, then you can trust their judgement if they feel it is safe to drive their kids to school. Unless of course you subscribe to the school of thought that people are incapable of sound judgement, and require the government to legislate it for them, but that is a red herring.
