What is the test for increased risk of injury in a motor vehicle accident?

"The second prong . . . refers to whether the movement subjects the victim to a substantial increase in risk of harm above and beyond that inherent in [the underlying crime]. [Citations.] This includes consideration of such factors as the decreased likelihood of detection, the danger inherent in a victim's foreseeable attempts to escape, and the attacker's enhanced opportunity to commit additional crimes. [Citations.] The fact that these dangers do not in fact materialize does not, of course, mean that the risk of harm was not increased." (People v. Martinez (1999) 20 Cal.4th 225, 233.)
