Back about 1960, the Aurora company manufactured a slot car/HO railroad crossing.
Then they marketed it with artwork depicting cars racing trains to the crossing.
Some of our Big Brotherly legislators grabbed onto that and, lacking the political traction to deal with larger issues, latched onto it as a voter-friendly opportunity to display their power. Needless to say, they successfully outlawed the crossings in a lot of jurisdictions.
I rather suspect that those laws are still in force.
