Maybe not a regular bike helmet, but if you are constantly riding around at those speeds you should get an actual DOT approved motorcycle helmet. Those will save you from fucking up your head in the vast majority of situations at that speed.
Even a regular bike helmet could help sometimes. It really depends on a lot of factors like how hard you slam into the ground, whether you roll or slide, the angle of impact, etc. It’s not so cut and dry, but I would imagine wearing any decent bike helmet is always at least a small increase to your probability of surviving in a bike accident.
