When the weather here in the Chicago area was around 60-75, and I wasn't running either the heat or the A/C, I was routinely showing 295 to 305 miles at the beginning of a full charge. I don't drive like a granny or anything. I just drive like I have the mother in law as a passenger, and even then I sometimes open it up just to feel the power.
The mileage estimates are based on your current MPG, not an average. There are about 6 different test cycles. A lot of people get on a highway and run at a fixed speed and then report their results. They can vary widely. Car & Driver has reported that EVs lose about 41% range in cold weather driving and 19% in hot weather driving. They are also based on using DC fast charge up to 100% to get those range estimates. One EV site says that VW's battery warranty is the same as Tesla's 8 years or 100,000 miles. But another site says this is to about 77% capacity. I'm not going to drive in such a way that the battery loses that much capacity.

Just as with ICE vehicles a BAD driver can waste up to 25% of range. I've never gotten as little mileage as the EPA rating suggests. I really don't have enough information on the ID.4 to know all that I wish to know.

I don't believe that the ID.4 has a heat pump. Tesla 3s sold in the USA (I believe) do not either. But Canadian models do.
I do not like the assumption that a 10% reserve is adequate. That is only 28 miles (at best). I want to be warned at 50 miles range, especially due to the lack of chargers where I live. I wonder if a person could buy a Canadian model and if it would have a heat pump.

Exactly, Because an EV is so Efficient with its "FUEL" it requires far less for any amount of given range.

The amount of Energy in our ID4 Battery at 80% SOC has equivalent energy potential of 1.8 gallons of gasoline and we can go anywhere from 160 to 250 miles from 80 percent SOC.

This means even small to moderate changes in our Driving Efficiency can result in very large swings of Potential Range.

If gasoline could approach anything close to 100 Miles per gallon, I don't think to many people would be complaining about $5.00 Gas.

VW has the XL-1. It gets 269 Miles per gallon. It's a four passenger. It cost $6 Million to make. VW was supposed to lease about 100 of them but I've heard very little since. It's a Diesel Hybrid with every feature needed to get that MPG. The first version got about 239 mpg. It's NOT a practical design.

To get 100 mpg an automobile has to have an extremely low coefficient of drag. It also has to have an engine that produces just enough to achieve a decent top speed. People today have gotten used to cars that regularly accelerate from 0 to 60 in 7 seconds or less. This was the performance of the typical sports car in the 50s. I was driving motorcycles that could do this is 2.1 seconds in the 70s. Today's EVs in general, have too much HP. This wastes range. That extreme performance is how some makers sell into this niche market.

When the Honda Insight first came out it was getting 72 mpg. After a software update for pollution this dropped to about 55.
