In general, there are no tax consequences when you receive an insurance payout for a totaled vehicle. The reason for this is that very few cars appreciate in value, so it is generally assumed that the car insurance companies will pay out the proper replacement value and that the value will be close to what you paid, or less (so capital gains would not apply). It's not uncommon for insurance payouts to be slightly higher than what you paid, and if that happens it just means you get a good deal on the car.
There are certain vehicles that do significantly appreciate in value, though generally they are specific desirable classic cars that are usually at least 20 years old, are in excellent condition, and have low miles. If you sell that type of car (or collect an insurance payout) for a significant profit you would pay capital gains unless you roll the profits into another investment vehicle. Further reading here.
