It's possible to animate a route with streetview and directions (version => 2.12k). Initiative, idea and sponsored by Andrea Torre! Thank you very much.
It's possible to add multiple via's (version => 2.12n),

For example:

{mosmap animdir='2'|address='Roma, Italy'|toaddress='Fiumicino, Italy'|waypoint[1]='Frascati, Italy'|waypoint[2]='Ciampino, Italy'|formspeed='1'|formdirtype='1'|formaddress='1'|animautostart='1'}
