Not even one map as jpg or png to see on the webpage!!!

Whats the point of this project? You expect us to load npm just to see some maps?!

Read the Readme.

They've linked to https://s-macke.github.io/Test-Drive-3-Maps/

this is not jpg or png but some dynamic stuff.

It freezes up my phone. Why do you need to complicate the stuff so much?

Direct jpg or png could be rendered even by pentium 100 with 32mb of ram...

Sorry, the maps are rendered in 3D so that you can fly around. I can of course make top-down screenshots of the maps. Thanks for your feedback.
