Losing in thought and autopilot kicked in Every day I ride my bike from home to office. It takes 1 hour journey.
During that hour, many times I found myself somehow teleported to certain distance. It is not magic, I simply lost in thought when that happened. I am so absorbed in my own thought that I am clueless to my surrounding, although my autopilot will guide me safely during that teleportation.

that is only an example of many activities where my autopilot kicked in. 

Problem is, I feel that it is a mistake to be lost in thought. I feel it is not supposed to happen. I feel I supposed to being in present moment. So to counter it, I try to being aware of my body movement, such as opening/closing gas, shifting up/down gear. I recite the word in my mind when the body move. After doing so, I came to realization that my body movement/reaction is faster that my mind.

the questions are:


Is it really a mistake to be lost in thought?
Is my way of countering have bad effect?

When Satti is absent you create fabrications hence future misery. Therefore, it is a "mistake" to be lost in thought.


  Is my way of countering have bad effect?


You are doing Kayanupassana hence this is one of the solution is being mindful, i.e., mindfulness of the body. In addition be mindful of the bodily sensation when moving like the fabrics touching your body, the wind sweeping over your skin, etc. Also look at muscular pains and pain and pleasure in changing postures.

Ultimately what you have to work with is to realise 4 Noble Truths and Dependent Origination this you can realise through any experience you perceive as good, bad and neutral and this leads to sensation which are pleasant, unpleasant and neutral and even the pleasant and neutral are unsatisfactory due to 3 Characteristics while unpleasant is unsatisfactory on its own and neutral opens us for further existence and it can still give unpleasantness in the future.
