> A conventional navigation system would tell the driver to turn right in 100 meters this is not very informative since drivers may not have an accurate sense of distance.

So, this is for the subpopulation of car drivers that have no accurate sense of distance? Mmh, okay.

> - follow the silver car to turn left

> - I can't see it

Not surprising. Colors are somewhat ambiguous, cultural and subjective. Greyish ("silver") is a very common color for a car. At this moment there were several car matching that description.

So, using color, at least in this case, is not accurate.

At least, with a distance, the information is somewhat well-defined.

> - okay follow the silver car in the leftmost lane

That's another silver car.

Wait, what's the benefit of mentioning that car, compared to saying "join the leftmost lane and follow it to turn left"? Or simply, "turn left".

Do they mean it is for drivers that can follow another car but not painted lanes?

What happens in low traffic when there's no other car to follow?

> turn left at the building with a billboard

There are several buildings with a billboard. One at around 100 meters, one at around 300 meters.

So, mentioning "a building with a billboard", at least in this case, is not accurate.

At least, with a distance, the information is somewhat well-defined.
