JonC:blakamin: And this:
is another reason current NZ rules are stupid. How many people do this (supermarkets etc) without causing accidents?
Yeah - especially this one. Most t-junctions like this have a give-way sign where the red truck is, but for the ones that don't people in the red-truck position still give-way even though they don't have to.
In practice they have to, because the blue car won't! I would say the blue car often (incorrectly, of course) takes the right of way rather than the red car giving it. I don't think changing the rules just because people can't/don't apply the current rules is a good reason.
