Too bad.

If you had used a regression not only would the value more likely
be unbiased, but you could drag out a confidence interval on either G
or M or both.

More generally, if you drop the requirement that M be constant you
might even get a ballpark on the local DM distribution.

[Summer's] our accident season. It's when people get stranded.
They break wheel nuts, blow tyres.
We had a chap in here two days ago, he'd blown four tyres on his vehicle
driving around in these temperatures.
You can imagine if it's 49C in the shade, we're talking 77, 78, 80 degrees
out in the sun.
I mean, you're running rubber on [the road] -- tyres just can't cope with
that sort of condition.
