I usually do stay pretty far away. Daily driving all the shitty cars I have in the past, it's become a habit to stay back. If I'm not staying decently far back, then I'm in something I trust and stay very aware.
On the flip side, I just rear ended someone for the first time in my life last weekend. Going around 5mph. LOL.
