The first campaign was to promote a piece of software. The second was to promote software as well "Alcohol 120". The third had to do with Viagra, the fourth, fifth and sixth had to do with PC games. Any idea why they haven't started?
But "The Need for Speed" (a PC game) - sensitive? Neh...
Just did a quick search on my favorite search engine to confirm that "Speed is the street name for Amphetamine. Like coke it's a stimulant that people take to keep them awake and alert. It's Britain's least pure illegal drug...."
So I suspect that 'speed' will fall into the 'sensitive' category as well. Even though you're using the word in an entirely different context, the system will not know that. An actual human being will need to make that judgment call.
I'm sure that everyone can appreciate the need to be careful in such matters, given that one's ads can reach millions all over the world in a matter of minutes - unless reviewed first.
