They are 2 cities in the UK that are ~220 miles apart, so 1 in a million people die every 220 miles driven

Good point! I was focussing on the UK since that's where the majority of AZ vaccine users are, but you're right. I'll swap in a more international first risk!

Maybe tonight I can work out do an IP address lookup and personalise it for your locality ;)

I guess you may be confused by the missing "from". It should be "driving from London to Liverpool", whereas the present phrasing suggests we move a city with millions of inhabitants.

That might actually be the problem - however, it's kind of a stretch to say it "should" be expressed that way. "Driving A to B" is a common phrase (as for whether it's technically correct, despite the ambiguity of meaning, I actually am not sure).

Not to be rude, but are you aware that Liverpool (like London) is a city? I guess I'm unsure what the confusion is.

London and Liverpool are major cities in England. 200 miles, 4 hours drive time, roughly.

Similar distance/time as DC to NYC.

Risk of... dying? Being injured? Being hospitalized? Developing a life-threatening clot? Also it's missing a word "from" but I worked that out. Thanks for your contribution.

Ha, none of us guessed right. I assume dying, since an analogy between other consequences of the two events would be so fuzzy.
