Step-by-step explanation:
The poor choice of genre for 'How to Prepare for a Road Trip' due to limitations in the amount of text would be Text message. Text messages have a limited number of characters and are not suitable for providing detailed information or instructions. It would be challenging to explain all the necessary steps and tips for preparing for a road trip within the character limit of a text message.
