Spontaneous rear windscreen smash

[scrubchub]

Neighbour just knocked on the door, said he was working in the garden and heard something that sounded like a bomb going off, lo and behold, it was the rear windscreen of my partners Qashqai:



No reason for it. Car was parked in our space, off road, and we live down a tiny track that has no footfall or traffic. There was no one around.

Anyone heard of spontaneous glass explosions before? The hole in the corner looks like something has hit it to me.

Thanks for the replies - along the lines of what I was thinking to be honest. Explanation of the layout (bear in mind that the plot has been developed, so even though it looks like I'm talking about a garden, it is now a gravel driveway):



My place is the blue dotted house.
My car park space is the blue box.
Neighbours car in the black box.
Gardening taking place in the red box.

Hopefully you can see that we are very nicely tucked away off a very quiet road, hidden around the corner of small, derelict house and backing onto a neighbours house. There is no way anyone else has been around there and done this, so the only realistic explanations are neighour or it has just exploded in the searing heat of this 19 degree Sunday lunchtime.

Ha, while I was writing that reply some others have posted! I'd rather it was just a freak spontaneous thing of course, rather than the nieghbour being clumsy, so I'll chalk it up to that. I'm not going to go around accusing anyone of anything anyway.

Was half the car in strong hot sunlight, while the other half was in shade?

Yes, pretty much. Broken glass in the sun, front windscreen not.

EDIT: £70 excess on insurance. Could be worse.
