@humantransit Agree it’s essential to check. I checked Google image search & it seems to have done better, see the attached screenshot. It depends too on which model you used. Here is what Claude Opus 4.8 High gave me also a screenshot.

@binarybits Traffic crashes increased nearly everywhere in the US during that time. % increase is insufficient to support their conclusions, a rate is a better measure. Waymo didn’t operate in whole city area, so restricting analysis to those areas or comparing them would be useful.

Entre enero y julio de este año, Bogotá fue la ciudad preferida por los visitantes no residentes que llegaron al país. La localidad de #CiudadBolívar y su oferta de turismo comunitario, de lo más llamativo de la capital.
