 #### Test 1: Simple Test of Localization
 
 Simply put, how localization works in an urban environment was tested and the results were recorded on video.

 We can see from video that there is a localization error in the longitudinal axis along the Eurasia tunnel. As expected, NDT based localization does not work properly here. However, since the NDT score cannot detect the distortion here, localization is not completely broken until the end of the tunnel. Localization is completely broken at the exit of the tunnel. I re-initialized the localization after vehicle exit the tunnel.
