European users will be glad to know Google added live traffic information for 13 European countries.
From the announcement: "The new road traffic information is in the traffic layer on Google Maps and Google Maps for mobile, and Google Maps Navigation (Beta). Today we’re announcing new coverage in Austria, Belgium, Czech Republic, Denmark, Germany, Ireland, Israel, Luxembourg, Netherlands, Poland, Slovakia, Spain and Switzerland. Coverage includes all freeways and highways, as well as large roads in major cities. Users in the UK will also benefit from a finer grain of street level coverage.
[...] The live traffic layer is regularly updated to show information for traffic events from the last 5-10 minutes. Finally, you can learn more about typical traffic conditions for specific times and days of the week by clicking the “change” link in the traffic legend on Google Maps, and setting the day of week and time."
