If my neighbours' children repeatedly leave their bikes / footballs / assorted crap on my front garden

[SunLolly]

Would I be unreasonable to accidentally drive over them (the things, not the children)?

And, more importantly, would this damage my car?

Yes and yes

I drove over a snowman built in my parking space - car was ok but I had to drive at it twice
And yes, I've driven over smaller toys but not actual bikes/scooters

Think I'd enjoy running over a snowman.

I sometimes park on the grass if I get home first but need to leave first in the morning, rather than parking on the drive and having to swap the cars around later.

It's a pain in the tits having to get out and move their crap before I can park there.

I would probably start moving them onto the pavement so they are a free for all. not your fault if they disappear!

Good idea Mrs H, but there is no pavement. It's just garden and then road otherwise I would do that.

Road sounds better - they might get squashed more quickly

Why are they on your garden? I would go and see the parents.

Well, I might have a word with the neighbours first; point out the kids should leave things in their garden not yours, you do need to use the grass for parking so could they remind their children not to put their toys where a heavy car is going to park, and that you shouldn't have to stop the car, get out, move their kids stuff out of your way, you should just be able to drive onto your grass? And that from tomorrow, that is precisely what you will be doing?

Yes I'd planned to speak to the parents first, the driving over is phase 2 of my plan.
