This is exactly what I have done and what I do. Like you, I have plenty of snow stories.
Whoosh
Eye see what you did there.
Karma times two:
I think we both got Karma on this one. This goes back to when the new plastic bills had just been issued and we hadn’t got used to the fact that they had a tendency to stick together.
One day I had taken a taxi from the train station to home. The fare was around $30 and I gave him what I thought was $40 and told him to keep the change. About 3 weeks later, my doorbell rang and when I answered there was a man. He explained that he was the taxi driver and that I had actually handed him $60, two of the bills having stuck together and he was there, a $20 bill in hand, to return the extra bill. When I recovered from my astonishment, I finally told him that such honesty must be rewarded and told him to keep it.
You know some people don’t know how to properly flip pancakes:

I believe I’ve heard this story before.

I suppose they deserved it, but with the bad weather they might have been seriously hurt, or in trouble. Call a tow service at least, or law enforcement.
The first time I ordered from a local pizza place(it was new then) I went to pick it up and immediately felt sorry for the girl at the counter. She hadn’t turned in the order correctly, so there was no pizza waiting. I told her I’d wait, as I work food service and I KNOW how stuff happens. She ran back and got the manager and he told me they’d make it at once and give it to me free, plus a coupon for my next visit. And oh, someone hadn’t picked up their cheesy sticks, would I like them? Free stuff? Sure! It’s the only time that place has ever messed up an order of mine, and years later I think they have the best pizza in town.
That was my gf’s POV when she heard about the situation. My POV respectfully remains fück those motherfuckers.
You were too restrained, in my opinion.
Ah, sometimes it can take a while. Depending on how naughty you have been in general, karma can take anywhere from a second to several lifetimes to get back to you. Be patient and non-naughty and you should be fine.
An opportunity to make up for your loss - with interest - and you chose to just cuss them and drive away? 
I was reminded of one today. A couple of years ago I was out on the bike - I just happened to be on UK National Cycle Route 21 - London to Brighton. I passed someone on a foldie, said a hello, and she shouted something back at me that I didn’t catch, so I circled back to find out what it was. Long story short, it was a Canadian lady who must have been in her eighties, who had flown in to see friends in London (bringing her foldie with her) and then had got it into her head to spend 3 days cycling from London to Brighton (about 60 miles). She had shouted to check she was on the right route.
I know this because we got to chatting; I decided to chaperone her because the route coming up wasn’t obvious, rain clouds were gathering, and she didn’t know how to get to her hotel for the night. So we chatted and I guided her to the door of her hotel, wished her well, and set off on the five or so miles to home.
I had got maybe fifty yards when the heavens opened and shat it down on me. I was like a drowned rat in seconds.
That’s the thing about the karma bank - the value of your investments can go down as well as up.

Back in the very early 1990’s when there were no smartphones or cell phones for that matter, my then girlfriend and I were driving down the highway towards our date destination. It was raining very hard and we knew that we were going to get drenched once we got out of the car. We passed a car that was pulled over on the side of the highway and noticed there was a person sitting in the passenger seat. Then not even a 1/4 mile later, we saw a guy trudging through the rain along the highway, attempting to use a very soaked newspaper to keep the rain off. We quickly realized he was the driver of the car we just passed. We also realized that he had at least another couple miles to read an exit where there was a gas station with a phone.
I pulled over and picked him up. He was drenched. He explained that his car broke down and he was going to the nearest gas station to make a call to get picked up. I backed my car to where his was and we picked up his wife who was the person waiting in the car. We dropped him off at a Shell station that was about 2 miles down the road.
They were very thankful. He gave me his card and said to contact him sometime, but he lived in the next town over. As far as I know I never saw him again.
I gave a guy in a boat a tow. The imperial palace in Tokyo has a most around it and there’s a spot where you can rent either row boats or those pedal boats. I was with my girlfriend in a row boat and a couple in a pedal boat called out. The pedal boats are deeper and they had run aground in a shallow part. They asked if I would tell the rental place when I returned the boat but i suggested we try it. Attached to the front bog the boat was a rope so I threw him the other end. They pedaled and I rowed and we managed to get them free.
It wasn’t that big of an act and I got the better deal by giving me an amusing story.
When I was a teenager, I hitched all over the country. Later on, in my 20s I had a driving job and gave many people lifts.
My most memorable story was the time I had a hired van making deliveries in Scotland - I was based in London. The van was unusual in that there was no separation between the front and the loadspace at the back.
I did my last delivery somewhere North of Edinburgh and picked a guy up who was aiming for London, although I was going to have to stop overnight on the way. South of Edinburgh, there were always a gaggle of hopefuls as one turned off the bypass onto that A1 South. I had a big space behind me with only a few empty boxes, so I picked up a young couple and put them in the back.
When I stopped for the night at a transport cafe, I let them sleep in the van while I had a bed, and they were still there in the morning. They even paid or my breakfast. At the exit there were more hopeful thumbs, one carrying a guitar. The 350 miles and 8 hours (busy roads and a slow van) went past in a flash as we sang all the old ballads and swapped stories.
I was so grateful for the diversion that I drove around London for a bit, dropping people off at the best places for them to carry on their journeys.
Maybe she was a time traveler and she thought that you were her Uber.
