So the news media is spinning this like it was a hit and run. I know from living in England it is very easy to get into trouble.
I was brief if you catch someone robbing your house, you should help them carry the TV out so they don’t hurt their back and sue you.
You can be arrested for carry a steak knife set from the store to your house... Very crazy legal system.
Who knows what a British jury or Justice with possible local resentments would do? In places in the US something like this—if she does not habitually have accidents—would probably result in a fine, drivers training, community service, loss of your license for a time. (Unless you used alchol or drugs.) (Then there is the Civil suit....)
I do not know what happens in Britain, but someone made the determination it might be better to send her home.
