Are you sure?

The Chinese traffic Surveillance cameras also photograph who is inside the Vehicles

yes, the driver, but not the passengers. I doubt he drives his own car.

If the cameras can see the driver, they can also see the front passenger. And who gets in or out of the stopped car. Istael/US probably analyzed months of footage to establish patterns and uncover their habbits and schedule.

Most VIP situations, the VIP person sits in the back. Luxury car brands like bentley or limos are specifically designed for a comfortable back seat. The backseat typically has much darker windows

Yes but they also make a show when they get in or out of the vehicle. Several bodyguards flanking them, opening doors for them, the driver getting out of the vehicle, red carpets etc. Khamenei was also wearing distinctive clothing to make it even more obvious.

neat, but most people have this show on private property and not on the street where the public cameras are pointing.

1) It's possible there are traffic cameras covering wherever they get into the vehicle.

2) It can be used in conjunction with other assets watching who got in etc...

It's also possible that they simply went ahead and hit the vehicle, knowing there was a good chance that their target would be inside. It's not like they've been all that picky about collateral damage.

Why risk starting a war and not be 100% confident where the leader is?

Risk starting a war !!

That was the whole freaking point.

The attacking forces doesn't give a flying F about Iranians otherwise the sanctions would have been removed long ago on humanitarian reasons.

Most wars are started without targeting the leader at all.
