No one aboard the train was hurt.
The California Highway Patrol says the Honda was traveling at more than 100 mph and weaving in and out of traffic
The Times reports the San Diego County medical examiner has tentatively concluded the driver was 24 years old and from either Squaw Valley or Costa Mesa.
