I think this is mostly what you want, but as far as I can find online (and I'll test it again later today) it no longer shows traffic warnings and your current speed like the destination maps does. I think it used to, though, which is what's annoying about this whole situation.
I actually lost this feature for a while - it used to be under the hamburger ≡ menu as "Just Drive" and then the hamburger menu disappeared, and I've just recently found it again as a widget.
So, yeah, Google kills all good things and I'm sure it won't last for much longer, but it's nice in the meantime.
If using Symfony, LiipImagineBundle can handle this.
Python's Pillow library might help here. Within node.js itself it looks like the sharp module could also suit your needs.
