Would it be rude to ask this?

I have new neighbours moved in a few weeks ago. Their parking space is outside my bedroom (long story). Their car is quite high at the back and they reverse in but it’s parked so close I can’t open my windows more than an inch
starting to feel a bit hemmed in as I love opening windows in the morning but it’s also my only escape route if there was a fire in the hallway…
would it be cheeky to ask them to budge up a bit?

It all depends on how you ask, doesn't it? If they're reasonable people and you explain the situation as you have above, and they can accommodate you, then I don't see why they wouldn't.

But pick your moment! E.g. when you're chatting.

If they have space to be a bit further forward without being on the pavement/road/whatever is in front of the space, then I don’t think it’s unreasonable at all to ask politely. They probably just haven’t realised.

If they moved forwards would they still be within their space?

Could you ask if they'd be willing to swap parking spaces with you?

They wouldn’t, my space is nowhere near. They’re also in the deeds so can’t really swap

No.

Can you open your window when they're out so they HAVE to park further forward? Then have a conversation about it.

Yes, it’s quite a long space and previous owners no issue

Yeah I could try that, I’ve been out most of this weekend but can give it a go! My window is a triple one where the middle doesn’t open but the two end ones are blocked
it opens like /—\

I’d just make sure the window is open when they get home so they get used to parking further forward without it becoming a battleground. Harder because it’s winter, but presumably only for a short period of time.

If your windows are open when they return will it block them from getting into their spot? Or can they stop before reaching the windows?

Yes I usually just open in the mornings while I’m getting ready for work
i have been struggling with anxiety recently and not having an escape route as such is making me quite panicky which I know sounds ridiculous

They can get in, I’ve lived here 22 years and had no issues before with any other car

Its not ridiculous.
In fact, maybe have a chat with local fire brigade about it. They may have some advice how to approach it

Then I’d maybe just try opening my windows whilst they’re out in hope that when they return they leave a bigger gap. Failing that I’d just ask them if they wouldn’t mind leaving a bigger gap and explain why. If there’s plenty of space so they can still get out I can’t see why they wouldn’t do that for you

I think it's absolutely fine to ask nicely. I could imagine someone thinking they were being "good" tucking the car right in not realising it was causing you and issue...except would a reasonable person actually park a big car right up against someone's window, whether it opened or not? Probably not! Just ask them nicely and add that it's making you anxious if they push back.

(I wouldn't do the window open thing, just ask them or put a super polite and nice note through if you can't face asking face to face)

I mean if they’re not parked there, I’m fairly likely to have my window open anyway just out of habit. My cat likes to sit hanging half out of it too
