Good: 0.1 miles is 528 feet. You probably pass 500 feet in the middle of the announcement.

Bad: oops, 0.19 miles is not 0.1 miles. :-)

As far as I know, a TTS system that is savvy in imperial distances should probably read out distances of less than a mile as follows:

1 or more miles = # of miles
0.5 = half a mile
0.2-0.3 = quarter of a mile
0.1 or less = # of feet, starting with 500 (0.1 miles = 528 ft; the 28 ft over 500 is really insignificant on the road when approaching a turn) and counting down.

Typically, highways signs, at least here in New Jersey - and this is most evident on construction signs, starting counting down feet at 1500, suggesting that really anything less than a quarter mile should just be measured in feet. I realize 1500 ft is a little more than a quarter mile, but I guess it's more obvious and concise - and probably easier to print - on a sign than a quarter mile.

Something is definitely funky with the distances to roadside alert pins. I don't think it's showing metric figures instead of imperial, because that would make things appear on the Waze map closer than they really are. Rather the effect is opposite; I drive about half a mile and it only counted off a couple hundred feet.

I think the developers need a refresher on math (or maths for the INTL people):

- Client speed knots to mph/kph rounding causes some values to never appear
- Segment length shown in the map editor causes confusion about U-turn surpression (less than or equal to x will surpress, but x.9 is shown as x so what happens then?)
- NA client showing feet/meter mix up for distance to hazards
- 500 feet warning at close to 0.2 mile instead of 0.1 mile.
- UR in the editor - Today? Yesterday? Who knows?

Makes you wonder what bugs are hiding in the routing code...
