I came across a Latvian guy who had crashed but didn't know the number in the UK for the emergency services. Thankfully he was unhurt otherwise no-one would have known. His car was quite out of sight, had he been injured he could have been there a long time before anyone knew. I found the very sad thing (I called the cops then let him sit in my car, It was friggin freezing) was that he said he'd been trying to get someone to help him for about 30 minutes before I pulled over. 30 minutes of traffic and not one pulled over to help. Pro-tip America, 112 works anywhere in Europe land-line or mobile phone, including the UK.
