Aerial driving simulator using google maps and question about roundabout.

SuperInfinity

I found this amazing aerial driving simulator that works using google maps: http://geoquake.jp/en/webgame/DrivingSimulatorPerspective/

Unlike google maps this is a surprising amount of fun to use. You can plan your entire route from your chair and never be unsure of the road/lane you need to be in again, provided they are marked properly. There is something about having the actual car that makes it so much better than standard google maps. I also don't think google maps can load itself as fast when you're in stardard web mode.

But I have a question about this roundabout, if you type in "wilton roundabout cork ireland" into the search box it will come up.

Look at the top left-hand side of the roundabout (the corner with LANA BUS marked to the far left). Now go on a bit from that to where you have two lanes. In the left lane there is one "forward/right" arrow, and in the right lane, there is just a "right" arrow.

Shouldn't such arrows indicate that you have the priority as long as you are following them? However if you are in the left lane then follow the arrow that is going to the right, you will be crossing over the discontinuous line. Similarly, if you are in the right lane, you can continue on your road without expressly "keeping right" as the arrow suggests... there is no ambiguous marking on the road that would require such an arrow. I don't believe that you could just cut across a line like that.

So what is the right-facing arrow in the left lane doing there? Is it to indicate that you may go across the lane, but you have to give priority to the cars already on it? I thought that you could change lanes anyway on a roundabout so long as you give priority to cars already on it? Maybe it helps the flow of traffic if they use this place to stop and switch lanes? If so, I never knew about that rule and don't see how I could.

I have gotten off at the wrong exit or went around again on this roundabout or similar ones. At first I thought it was my fault for not reading the signs properly or for getting paranoid about what I could or couldn't do, but as you can see here, sometimes it's ambiguous. Sometimes lines are faded away on the roads. Even with a perfect view of it from above, it's still not perfectly clear with 100% certainty how it should work.

Wow, for something so seemingly boring I've been driving around for hours, booming through my estate 120kph!

This is a spiral roundabout with incorrect markings. Someone assumed that because there are two lanes that they could mark both as right, even though one is a newly formed lane on the spiral and the "straight ahead/right" lane is leaving the spiral and should be marked straight only.

It appears that not only do most drivers not understand spirals, neither do the council... you may want to report this to CCC.
