I hope they do long term testing.
The early plasticized paints used for lane marking in the US were not properly tested before being used extensively and the taxpayers of the US have been paying the price for that miscalculation for over 20 years.
Incomplete testing resulted in tens of thousands of miles of damaged roads with miles of elongated pot holes the shape of the lane markings after a few winters. It seems the paint, lauded for its durability and ability to bond with the pavement, weakened the pavements ability to handle freeze / thaw cycles.
I hope they are smart enough to do long term testing with this or lots of hype could get very expensive.
