Don't be stupid all your life.
If God allows you to have the finances to afford an SUV, it certainly wouldn't
be a sin to drive it to church, alone or with a crowd of sinners. The scriptures
say, "He that comes to God he will in no wise cast out."
Anyone with any Christian intelligence should know that Judgment Day won't
be concerning anyone's driving record.
Perhaps you feel that way because they won't come and pick you up. I can see why.
