Actually, it's not. It's Murder 2, or Murder in the 2nd degree. Premeditation is Murder in the first degree. All that's required for murder is a) intent to harm (not premeditation), and b) death. Given that running over someone kills them, this is definitely attempted 2nd degree murder.
Edit: I forgot, intention to commit a felony carries premeditation, so it would even be attempted first degree murder
Typically premeditation determines 1st vs. 2nd degree murder.
Intent to harm without intent to kill typically corresponds to (voluntary) manslaughter. Reckless disregard or negligence of the potential for death may result in manslaughter or some lesser charge like involuntary manslaughter.
This differs by state; some have crimes like "3rd degree murder" or "2nd degree manslaughter", or "voluntary manslaughter" vs. "involuntary manslaughter".
There are also delightful variations where someone "sufficiently provoked" (adultery being the traditional example) would face manslaughter charges for what would otherwise be murder.
Given what little we know there is no suggestion of an actual intent to kill. Without such an intent how can you possibly suggest attempted murder? You have overreached massively. The logical conclusion of your reasoning is that any assault with a deadly weapon amounts to attempted murder.
In California it seems quite likely to be second degree attempted murder and aggravated battery; even if it was only the second, those offenses, taking into account the potential enhancement for great bodily injury enhancement, have overlapping ranges of potential sentences, so neither is necessarily more severe legally.
