Fixed that for you.
But yes, I thought it was a missed opportunity. The bulk of road death, it seems to me, is pointless and unjustifiable - it's not caused by people on their way to emergencies, or responding to life or death situations, for the most part. It's caused by failure to read the road ahead, and wilful lack of attention to the road and anticipation of hazards.
I dunno about missed opportunity - it's just a play, written by a writer, not a public information film. Yes, we all have axes to grind with various types of driving, but the writer may not. Or in fact he may have an axe to grind about police cars speeding through towns.
Also, although we'd not seen the rest yet, I think the details of her death are not meant to be important. What's important is what happens to the family afterwards. She could have tripped off a station platform in front of a train, or had a sudden heart attack or stroke (it does happen even to seemingly fit young people), or been electrocuted by that Casualty toaster. All that matters for the drama is that she dies, and suddenly.
If the later parts include a lot of stuff about persuing the police, then I'd suspect the writer had a motive. But we've already been told that the police aren't denying responsibility, so that seems unlikely. I think to make a point about dangerous driving, you'd need to concentrate much more on the circumstances and the driver involved.
Also, I think a one off play, or short drama series like this has limited opportunity for axe grinding or education like that. A soap opera is probably a much better way to get a message over to a lot of people, because you can develop characters, and then cover the aftermath, for much longer. Sadly, many soaps prefer to go for big one off disasters these days.
