As long as your driveway isn't the on-ramp to the highway and your fluids have time to heat up a little before you start your 4k cruising, truly don't sweat it. There's another 3500 rpms available to the engine, and you're looking at likely several years and tons of miles before you can even lightly perceive any sort of effect on your engine due to wear. I mean, are you cruising/commuting for 4 hours or something crazy like that?

You're less likely to have problems doing your daily cruising and good regular maintenance than the person who only drives it for a few hundred sunny-day-only miles in the summer, barely lets it stretch a leg, and packs it away the rest of the year like it's a $20 million Ferrari GTO.

The only thing that'll really be hurting from sustained 4k compared to sustained 3k is fuel economy. Just the price to be paid for quicker acceleration. Of you have to cruise at higher speeds to avoid being anhazard on the road going 20mph slower than everyone else, so be it.

Awesome, thanks!

This is for about 15-20 mins at a time. I change my oil every 7-8K km and check the level every couple of weeks. My place is VERY close to the on ramp but I keep it at or below 3K rpm until the temp needle is past the second notch on the gauge.
