Not wanting MIL to drive children 3hrs

[fourlegstwolegs]

DH wants children to stay with MIL for a few days. I have no problem with this at all, she is great with them and they love her.
HOWEVER - she lives almost 3hr away, her car is small, she isn't a great driver and she's elderly. Plus the roads between here and there are notorious for horrific fatal crashes (lorries taking out entire families etc).
I said I had no issue with them staying with her, but that I'd drive them there myself and then pick them up again a few days later. I have a bigger, safer car, I am a much better driver (professional driving qualifications) and it makes me feel more comfortable with the risk if I am managing it myself.
DH had a fit. He thinks it's a personal insult against his mother (it is not, it's just fact) and says I am not being rational because the children do sporting activities that carry more risk (he's into statistics) and that if I am prepared to let them do XYZ activities I should let her drive them 3hr each way. He's blown a small issue into a massive deal and won't drop it. Has been bringing it up repeatedly for almost two weeks, is claiming that it's causing him sleepless nights etc, and that he cannot accept my "stance". It's exhausting and I just want him to move on! AIBU?

Using a cushion is illegal... And it was mil wearing HER specs to help fil do the driving!!

under what regulation is using a cushion illegal ?

Found this...

Not read all the posts , but i would feel the same. That is a long drive for anyone, regardless of age, but to add young children in the mix when you arent used to driving them would be a no from me. Is your husbands strange demands driven by the fact that he doesnt want to do the drive and if you do, he should offer to do one of the trips? It is his mum so should be the one to facilitate visits

He's still ranting about it!? For goodness sake...

Would your MIL let you stay for a bit too, and give you a break from DH?

I would be delighted if you offered to drive my gcs to stay, especially if you have a bigger car for long journeys. Your dh is being unrealistic, tell him that his dm is very kindly having the dcs but it's a long drive when you're not used to having dcs in the car.

yes, that is advisory as to position re seat belts. there is nothing to say seat cushions are illegal.

Children get sick or feel sick with MILs driving. That's enough to make the decision if it was me.

DH uses data to make decisions? So does Dominic Cummings and look where that has got this country.
