My 10 yr old doesn't use a car-seat. Legally, she doesn't have to, but my 6 yr old has to sit in a booster seat. Meanwhile, a toddler has to sit in a harness car seat, and a baby in a special infant seat. They all get different seats based on the ages. And none of them can sit in the front seat like an adult can. Everyone has an appropriate seat based on their age.
Sometimes as Christians we can judge other Christians on where they are "sitting." Yet all Christians are at different places along the way. Some may be in the infant car seat, others in a booster or perhaps even some in the front seat.
The apostle Paul puts it another way. He explained that some Christians needed Spiritual milk, not solid food because they weren't ready for it. They were still worldly. (1 Corinthians 3:1-3)
Where are you on your Christian road? How about those around you? If you are a a mature Christian, don't judge those newer Christians around you by the same standard you hold yourself too. They are still drinking spiritual milk.
Instead, why not consider coming beside them and inspiring them. Teach them the elementary truths of God's word and help them move up to the next seat. And remember even if you are in the front seat, it's Jesus who is in the driver's seat.
Hebrews 5:11-14 -- We have much to say about this, but it is hard to explain because you are slow to learn. In fact, though by this time you ought to be teachers, you need someone to teach you the elementary truths of God's word all over again. You need milk, not solid food! Anyone who lives on milk, being still an infant, is not acquainted with the teaching about righteousness. But solid food is for the mature, who by constant use have trained themselves to distinguish good from evil.
