Which is More Effective?

I recently had a discussion with a colleague about the famous texting-while-driving PSA from Britain (below).  I was impressed by its unflinching take on its subject.  I think it’s one of the best PSA’s I’ve ever seen.  He then turned me on to the second one, also from Britain, which also has safe driving as its focus but takes a decidedly different, softer approach to the subject matter.  I thought they were worth juxtaposing because of the contrast between the two.  I think both are well done but feel the first does a better job.  Which one do you think is more effective?
