There's no specific information on a "car plows into crowd into nightclub Hollywood" incident resulting in 30 injuries. However, I found a similar incident outside a nightclub on Old Klang Road in Kuala Lumpur where vehicles plowed into a crowd, but the details don't match the Hollywood incident you're asking about.¹
If you're looking for information on a specific incident in Hollywood, could you provide more context or details? That way, I can try to find the most accurate information for you. Vehicle-ramming attacks have occurred in various locations worldwide, including the US, resulting in injuries and fatalities. Would you like me to list some recent incidents²?
