Here's a fun one to keep in your pocket for the next slow moment in the showroom.

The European Union is reportedly preparing to expand Intelligent Speed Assistance, the system that currently just warns drivers when they're speeding, into something that physically stops a car from exceeding the posted limit at all. Using GPS, map data, and cameras, the proposal would make hard speed limiting mandatory in new vehicles by 2030. A temporary override might exist. Details on how, or for how long, remain unclear.

Listen to today's Automotive State of the Union episode for the complete discussion, additional context, and the conversations that shaped our perspective.

Here's the twist that makes this more than just a "big brother" headline. The mapping data behind these systems isn't close to reliable enough yet. Thatcham Research found current Intelligent Speed Assistance systems correctly identify speed limit changes only 74.3% of the time.
