to not want elderly in-laws to take DC out in car

[Abihattie]

Oh crikey. I feel like I'm moaning about my in-laws again but I could do with some advice please.
FIL is 81 MIL is 76. They're not good drivers. FIL has poor co-ordination (IMO) MIL has problems with her knees. They want to take my 2yr old out in their car and are talking about buying a car seat. I just feel so uneasy about it. Not just because of the driving but she's at a stage where she runs off if you don't keep hold of her.
I know I'm probably being a paranoid mother but I would be on pins. Worse thing is - DH thinks I'm being irrational and unkind and that she'll be fine and if I say anything they'll be really upset. So obviously, I haven't got his support with this.
Am I really BU about this? How would you feel and how would you handle it?

WRT the loss of conciousness due to the heart problem-I know FOR A FACT that ONE loss of conciousness for a medical reason means that you have to give up your license and re-apply for it when you haven't had a single loss of conciousness for a year. After my FIRST epileptic seizure, I was made to surrender my driving license. And while I was seizure free for long enough to get my license back (52 weeks) I had a seizure at 54 weeks, and there and then decided that even if I never had a seizure again, it just isn't worth the risk. So if anyone is driving after a loss of conciousness that hasn't been reported to the DVLA, they are breaking the law, and invalidating their insurance, and can be prosecuted for those offences.

And OP, YANBU, I wouldn't either, I only let my mother drive the DC's (mother and stepdad both in mid 40's). Mother passed test 1st time, stepdad scraped his test on the 5th attempt, and is just IMO a dangerous driver (think wrong way round roundabouts etc).

YANBU, I could have almost written your post, plus combining it with Coldhands.
MIL finally learnt to drive, they couldn't afford it , holidays, etc (?),eather until FIL's Parkinsons got so bad he kept freezing and driving into the back of vans. MIL comments after she finally passed her test was 'Well I can drive how I like now I've passed!' .
She insisted pushing the 3 wheel buggy when he was 6 weeks old, having been warned against going up stairs with it, she went for a single step full speed and luckily DP was the right side to catch the buggy as it v.nearly tipped over. My SIL leaves her LO with her 2 days a week, I don't know how she does it, couldn't.
But it's all fine according to DP, because she was stuck off used to be a midwife

Loudlass - I honestly don't know the ins and outs of it. I assume he was given the all clear - the black out was quite a few years ago now but I don't know. As I said he rarely drives now. My mum was the same, had a stroke and developed a mild form of epilepsy (petit malor something). She went back to driving, again I assume it was all above board.
