Americans

Don't some people in the UK talk about 'car hire' too? It doesn't sound in the least bit strange to me.

I do but maybe that's because I used to live in Canada? It's so hard to be objective about your own language use. I'll have to work it into a conversation...

1. They're much less common in the US than in the UK. I think "traffic circle" is probably the most common US term although where I live the few that exist are more often called roundabouts.
   
   2. It's just the trunk, not the rear trunk.
   
   3. We rent a car in the US. Hiring a car is unknown here.

That would explain why 'car hire' doesn't sound strange to me!

It would seem that both 'rent' and 'hire' are used in British English.

#1 in Boston is a rotary. Most other places it's a traffic circle.

1. Roundabout
   
   2. It's just a trunk whether it's in the front or the rear.
   
   3. In the U.S. we don't hire cars, we rent them. An extended rental for a set period of three, four, or five years is referred to as "leasing a car." We only hire people.

1. "Traffic circle" or "rotary". Except for some eastern cities they aren't very common.
   
   2. Just "trunk". You might hear people say "in the back" meaning "in the trunk", but never "back trunk".
   
   3. We "rent" cars (or apartments, or tuxedos) and "hire" people. A car that you rent from an agency is a "rental car".
