Less than a month into the trial there's already a large stumbling block: the roads go dark when they get too wet. More specifically, moisture, such as that encountered during rainfall, can quickly reduce the effectiveness of the glowing paint's light output. The engineers at Heijmans, which is behind the pilot program, say a new version of the glowing road markings is already in development and will be ready later this summer. Maybe the second iteration of the glow-in-the-dark roads will work as expected. Which then leads to the question of whether the future will include glow-in-the-dark roads. Seriously, our roads might just start to look like something out of tron if you throw the new 2015 BMW i8 into the mix.
