What risk? Sometimes government officials have to do somewhat unpopular things. Elected officials are just supposed to represent their constituency, though. If they aren’t willing to take a risk to serve their constituents, they shouldn’t be in a position of power. If you really believe it has to be done, and you really are in it to serve, you’ll accept the cost/risk. If that scares you too much, you’ll stay home.

And you can bet there’d be FAR fewer collisions if the spikes were present. Driving isn’t a right any more than having political office is, so it’s perfectly reasonable to expect people to accept the risk if they want the benefit.
