It's not just that the Tesla driver ignored the turn signal, but it also ignored traffic conditions. Left lane traffic had slowed down enough that the Tesla is seen passing 2 cars on their right before hitting the truck. California law puts responsibility on all drivers to be drive at a "reasonable or prudent" speed given the conditions. Maintaining a speed where you're quickly passing cars on the left and right — and not slowing down at all despite a vehicle signaling for 3 seconds and then fully being in your lane for about 1 second — is arguably not "reasonable or prudent". https://leginfo.legislature.ca.gov/faces/codes_displaySection.xhtml?lawCode=VEH&sectionNum=22350 https://leginfo.legislature.ca.gov/faces/codes_displaySectio...
