I don’t think that’s correct as there’s very little difference in surface temperature between the poles and equator on Titan. It probably has more to do with Titan’s long seasons and it’s axial tilt. In any case there are equinoctial storms in Titan’s tropics, but the liquid methane seeps into the dry surface. There is some evidence that it flows back poleward within subsurface aquifers.

Is there any corroborating evidence, such as dash cam footage, that the van driver actually had to slam the breaks? Very worrying case.
