(Cars and Drives Mod is officially supported - the cars drive much faster on the road blocks than on any other block)
I am Canadian, and so this mod reflects the roads where I live. The roads are accurate (well, as close as you can get in minecraft) to Canadian and American Roads (They are both the same). Soon I will update the mod to include road lines from other areas. For now, please have fun with north america.
Q: WILL THERE BE A 1.7.10 VERSION?!?!?!
A: No. Do not ask. I'm sorry. Actually I'm not sorry. But I'm still sorry because I'm Canadian. Sorry.
Very clean looking mod! I love the little details like the storm drains, and the assortment of signs. The road blocks lying slightly lower than vanilla blocks to create realistic sidewalks is a great touch too. If you do end up making that 1.7.1 version, i'll pop it on my server. All my buds are interested in this too (we like making transport infrastructures: planes, trains, cars). Good work!
