I couldn't agree more with Ron Kirby’s letter (4/11/21) about the dangers of “smart” motorways, and his suggestion that people should write to Grant Shapps with their concerns.

There used to be a very offensive “safety” advert showing two human-faced insects crushed against a windscreen, urging the driver to pull left on the “smart” motorway because of engine problems.

I am hoping this advert has now been removed; I used to wonder how relatives of people killed on these motorways felt when they saw such insensitive treatment of a potentially life-threatening situation.
