I found new Google Maps slow, useless (routes with only two points) and wrong. Is there any way, I can turn it off completely and go back to favored old Google Maps? Or is this — as with everything in Google — one way trip?

I found Google Help text on this matter, but it seems useless. I have the feeling, that it discuss something completely different. It says about lite indicator in bottom-right corner. I don't have something like that. And provided links, that should switch new Google Maps engine between WebGL and canvas-based, simply doesn't work. All of them opens new window with annoying advertisment about new maps.

I even tried pasing part of URL, they're talking about (force=canvas) into any URL that my new Google Maps uses. Of course without any luck.

So... is there any way, I can get rid of new Google Maps, once and permanently?

UPDATE: In these days (April, 2015) Google has announced, that soon new Google Maps will be the only one available. To my extremely negative surprise, this question will become invalid soon! :(
