Winter range loss: Is it really that bad, or just overblown?

I keep seeing people freak out about winter range loss, and I’m starting to wonder if it’s actually as bad as everyone says. I’ve had my EV for two winters now, and I’m only seeing about 15-20% drop on my commute, even with the heater running. I know pre-conditioning makes a huge difference, and I park in a garage. But I also see folks saying they lose 40% or more if they don’t have a heat pump. Is it the difference between older models and newer tech? Or are some people just not adjusting their driving habits? I’m planning a longer road trip up north this February, and I want to know if I should be genuinely worried or if the horror stories are just from people who don’t prepare. What’s your real-world experience?
