It's possible they don't really skyrocket. However, right now insurance rates are not at all cheap. It's not at all uncommon to have to pay $100+/month on insurance, per driver. For most families, there aren't many things they're willing to spend $1,000+/year on. When it's no longer a necessity, I would suspect that even if prices don't go up, because the marginal cost of driving yourself will have increased (cost to drive - cost of next best alternative, i.e. autonomous driving), most people will choose not to self-insure. Just like in some cities, the marginal cost of car ownership is so large (even if it's only a few thousand dollars more than in a suburb) that it makes more sense to rely on public transit.
