@Imari If this game is dead easy I must really suck.
We all sucked to start with.
But even the most authentic sim is easy if you drive within your limits. I couldn't drive a V8 supercar at race speeds in real life, but I bet I could trundle around the track not pushing it too hard just fine. I couldn't race a Zonda around the Nurburgring, but I could drive it to the shops.
Drive slower and keep the car on the track. Turn the AI down to whatever level you need to in order to make it so that you win if you stay on the track at a safe pace, but lose if you stuff it into a wall. You'll feel like a bit of a berk playing the game so easy, but stick with it. Once you're keeping it on the track you will develop rhythm very, very quickly. Give it a couple weeks, and if you feel that you're struggling now you'll likely be slashing seconds off your laptimes.
The thing I don't like about rewind is that as an assist it doesn't encourage the player to learn to drive properly. ABS and TCS (mostly) just slow you down, so there's incentive to do without. The driving line is far from optimal in most situations, so you're better off using your own judgement. But rewind encourages going at 110% knowing that if/when you stuff it, you can just try again.
Crashing being a big punishment should be incentive for people to drive in a manner in which they do everything they can to avoid putting themselves in a situation where they might crash. Unfortunately, most people don't seem to think about it this way.
Contrary to what we see in movies, driving fast is mostly about driving at 90% with great precision. Most people can get around a track at 90% quite safely, but because they're not very good drivers their 90% is relatively slow. What they don't realise is that by doing that repeatedly, they develop a feel for the car that is making them able to go faster and faster.
Instead, by driving at 110% they get no rhythm and very little feel for the car, because they're always beyond the limit instead of learning how to lean up against it. Being able to save a car is a useful skill as well, but if you can be consistent and not put yourself in situations where you need to save the car, you'll be better off over a long race.
I'm quick enough by most people's standards, but not alien quick. I tend to be 2-3 seconds behind the real aliens, or about top ten percent of most leaderboards. But I used to be a lot slower, and I got better by learning not to try so hard and taking my time to develop a feel for the car. And I did that by driving slow and safe and steady, which let me practise and reinforce the good parts of my driving.
It may not work for you, but it worked for me and I've seen it work for others. You have to slow down if you want to speed up.
P.S. This applies to anyone with a wheel or a pad. A pad is a perfectly capable driving device, but again you've got to take the time to develop your skills. Slow down, and focus on being smooth and clean. It's harder than with a wheel, I'll grant you, but it absolutely can be done and it's not really that difficult. Practise driving safe, and before you know it you'll be driving just as fast as you were before, but without twitching and crashing all over the place.
Don't neglect adjusting your equipment though. Pad and wheel input settings are a big deal (and it appears that the defaults on console aren't that great), so if you haven't done so already, do take the time to learn how they work and adjust for your own benefit. It'll make things a lot easier.
