I haven't had a chance to check it out on the web version but the mobile version works great. I am using it on my Nokia E71 with integrated GPS and the results are pretty accurate.
Other services providing driving directions in Delhi are:
1. Nokia Ovi Maps (http://maps.ovi.com) available on Nokia phones and on the browser for free.
2. MapMyIndia - available on the browser and also on Mobile/PNDs but not fully free. They also power the Yahoo India maps.
3. Amaze GPS - amazingly capable mobile GPS application available as a free download. An ad-driven service with no subscription fee involved.
Let me know if you know of any other such services and also if the Google Maps Directions are available in other Indian cities.
