Many thanks to Angel for the heads up that HRE Wheels has photos posted on flickr from the Michelin Pilot Experience event. The photos are spread over several pages in their photo stream and you will have to scroll through them to find the ones with Keanu.They start here, half-way down the page.
HRE Wheels has posted a piece on the Michelin Pilot Experience that was held in Palm Springs in January which gives some context to the photos. There is also a gallery of 42 photos which are smaller versions of the ones on flickr.
