They will have to come up with a surface treatment that can solve that problem, I’m guessing.

Excellent guess...

Longitudinal grooving works well, but on I-84 east of Boise they did transverse grooves. That'll drive you crazy!

In the trade, the practice of etching the groves in wet concrete pavement is called "tining." It is done by a machine immediately after the slipform paver places the concrete. The groves provide miniature drains to channel rainwater off the road surface. Concrete roadways, are, in my opinion, much superior to asphalt in this respect. Asphalt will rut over time and act to collect the water, causing hydroplaning.

The downside to the groves is greater road noise.
