This is what it says exactly in their warranty terms:
"The Battery, like all lithium-ion batteries, will experience gradual energy or power loss with time and use. Loss of Battery energy or power over time or due to or resulting from Battery usage, is NOT covered under this Battery Limited Warranty."

Some battery life loss can't be avoided, it's the nature of batteries. This, however, shows a study that was done on 500 different Tesla's and it shows that on average the batteries lost about 5% of their capacity at around 50,000 miles and 8% at 100,000. That's actually pretty good. Gas cars will see the gas mileage decrease over the years as parts get old and wear out.
This study shows the average loss is 23 miles of range for every 100,000 miles driven.
Now, all this said, these studies on are on the S model, not the 3 model, but I have a feeling the battery life will be similar and it won't lose 50-75% like you suggest.
