Even when riding a motorcycle, hitting stationary traffic is no fun! Handy, YES, but it's not really fun. It's a million times worse when you hit still standing motorways when driving a car.
Here's a web site that will help you avoid these bottlenecks. Frixo gives you full and complete road situations in real time. You can select the geographical area in the UK, a city or even a popular road, and the site shows you a map with all the difficult areas, like slow speed, accidents and work in progress.
The site is free, and you can use the information on your own website. There's even a mobile phone version for when you are already driving and need to consult he traffic.
