Also nuclear waste doesn't have to be a problem. If anyone was willing to cover the cost of burning it in a breeder reactor for power or burry it forever. It just is because it's expensive.
But it is a problem. Finding a place that can contain radioactive waste for millions of years is incredible difficult. If you read up on it, you get disillusioned pretty fast.
I agree with you, had to read it twice to make sure they don't mean to remove speed limits.
After a quick search I found a different article from BBC about a speed limit that is dropped from 30 mph to 20 mph. TIL.
