Probably not, but who cares. :P
Well, if you don't mind spoilers for Undertale's True Ending, now you can find out.
Once the monsters in Undertale reached the surface, I imagine there was a period in which not everyone knew that they existed or what they could do. The police probably got a lot of calls about weird but benign magical events happening in once-mundane neighbourhoods.
I could see Sans taking advantage of the situation to confuse, alarm, and generally weird out a lot of people.
The look on this poor officer's face was totally worth the speeding ticket - assuming Sans didn't just teleport away while he was writing the ticket, leaving the human wondering if the whole encounter was just a weird hallucination.
Sans: making blue lives weirder since 201X.
