I am looking for a Gazebo world to test some SLAM algortihms for autonomous driving. Do you have something to propose?
While not addressing your question about Gazebo, I would suggest checking out the LGSVL simulator (website, GitHub). It has several realistic environments and support for different sensor arrangements. It supports Autoware AI and Autoware Auto, but can be used with ROS/ROS2 without using a specific Autonomous Driving stack as well. It can definitely be used for testing SLAM algorithms.
