You're a star getting 4 kids to school every day, let alone when one has SN.
As someone else said, it's a bus ride, not a party, it doesn't matter whether he's unwelcoming or not (obviously nicer if he is!!). But it's your right to use public transport if it's running - especially to access 'essential' things, such as medical appointments, work, essential shopping and school
Whether it's one stop or 10, use the bus when you feel you need to (4 kids, DD's SEN & pissing rain I'd feel the need to).
I do understand the driver feel scared and irritated if he feels people are unnecessarily putting him at risk (and, like many, he probably can't afford to give his job up if he's not happy) so whilst he was very rude to comment, I can kind of understand him snapping. 4 kids getting on the bus, fir a short distance, probably does seem pointless to him & you placing him at unnecessary risk... but it's just another reminder that we don't know what's going on with other people when they're doing things that seem selfish or irresponsible.
My cousin is a bus driver. He's mid 50's and he's getting very fed up of people not wearing masks, and lots of young lads arsing about on the bus often with a few cans. It seems like it's a way to meet up with mates, but the bus company won't do Jack shit about it and despite being well able to 'sort them out' if he had to, he knows he'd be the one 'in trouble'. So all he can is try to ignore it.
But YOU do what's best for you & your kids! Get the bus to & from school with them if it makes the difference between DD coping & not. Or you coping or not.
I would get the kids that are able, to wear masks though.
Take care of yourself in all of this 💐
