Driver-side mirrors on non-US/CDN car

[Kar98]

I'm pretty sure that the law in the US and Canada doesn't allow driver side mirrors with optical effects like on the passenger side, as evidenced by the fact that passenger side mirrors are required to bear the warning about objects in mirror being closer than they appear.

I'm also pretty sure that I've had cars in Europe with driver side mirrors that had less of a dead spot than North American models, at the cost of the contents of the mirror being reduced in size.

The dead spot in the driver side mirror of my Yaris is deader and larger than any other I've had so far, including a full-sized Chevy van. Does anybody know if the mirror on mainland EU models is curved, or flat like in the US? Has anybody tried getting some for use in the US?
