Why do buses have lap belts, but cars have 3-point seat belts? ?
Since they are both types of motor vehicles, why wouldn't they both have the same types of seat belt?

Because buses are some of the biggest, heaviest vehicles on the road. That means that whatever it collides with isn't going to slow it down nearly as suddenly as when a car strikes that same whatever. It's simple physics. Because of that, for buses, it's been found to be beneficial to have lap belts to keep the occupants in their seats during a collision but that whiplash and the various injuries that shoulder straps prevent are rare enough for bus occupants that having the shoulder strap actually creates more problems for bus passengers needing to promptly escape the bus after a collision that they end up doing more harm than good.
Now pair that with injuries that occur from bus passengers getting snagged on shoulder straps and falling or otherwise injuring themselves in day-to-day use while getting up and down from their seats while the bus is in motion and walking up and down the aisle. I mean, you never get up and walk up and down a narrow aisle in your moving car carrying purses or bags of groceries or whatnot and navigating through vertical seat-belt shoulder straps on both sides of you every few feet that you can easily catch yourself on.
A lot of research has gone into this. It's not a double-standard. Research has proven that not having shoulder straps on buses is actually safer for passengers because of the physics involved in bus crashes and because of differences in how buses are used.

Because buses don't expect you to use them. Lap belts are useless, they might save your face in a crash, but rupture internal organs.

I was just in Europe and some of the tour buses had lap belts and others had 3 point seat belts.

If buses had 3-point belts, the belts would be a useless tangled mess inside a day.

Cars are more dangerous. And 3-point belts cost more than lap belts. Cars are so dangerous that they need them. Buses are safer, so lap belts are good enough.
