I bet if you said this 100 times it would still be just as hilariously

What on earth are you actually trying to say?

But you've got red ones pushing you from behind and EVERYONE knows red ones
are faster!

I dunno what I was worried about!

I'd reckon that the trip computer doesn't even HAVE a flow-meter! (Or at
least doesn't have one that measures flow that accurately)
I reckon it just measures the RPM and throttle position (and maybe 10 other
inputs) and gives you the pre-calculated result.
I can't really believe that anyone at Holden thought that having the
litres-per-hour readout absolutely-accurate would be anything worth spending
any money/time/effort on.
But then I'm a natural sceptic.
