Ironically I think this change in design makes it actually impossible, since now both lines appear to be tyre treads and they still come too close together.
The treads can come close together if the rear wheels lock up and the car twists/drifts, but the pattern in the sign is still “practically” impossible. Eg I can’t think of any movement a car could realistically do to make that pattern except maybe if the driver pulled the handbrake on then the car was buffeted by a tornado in random directions.
We don’t know the perspective or the contours of the illustrated road well enough to say this. I could imagine some perspectives where this actually works out, especially if the tires are causing the vehicle to slide sideways.
