Ah, I thought Detroit would be colder than that mid-winter. As for traction on ice, if the vehicle is already on the ice, it’s too late to slow down. I wonder

Ah, I thought Detroit would be colder than that mid-winter. As for traction on ice, if the vehicle is already on the ice, it’s too late to slow down. I wonder how the cars could know when they are coming up to ice. Humans can rarely know, but have some complicated ways of identifying, I think from glossiness? And ice is much more rare than snow/slush but both can be present side by side. Either way, I think they will figure it out. Sand can be awful to clean up in urban areas when too muh is used.
