> I might do 80-120 kilometres in a day and where I go there's no public transport

Yep, just what I thought. We have offsite duties too sometimes, 100 to 200 kilometers away, but we mostly end up renting a big car for such visits.

> unless I happen to be overseas and then I'll use it here and there if needed

That's a different scenario, even when I'm out of town the means of transport I use may change by quite a bit. 

I remember when I was in India with my father just over a decade ago, we had to switch things up altogether when it came to our day to day transport. In Kolkata it was either a taxi or hand pull rickshaw, but in Delhi it was the metro that seemed like a better option.
