I can provide some insights based on the information available up to that point.
The Coronation coach you mentioned is likely the Gold State Coach, a historic carriage used for British royal coronation ceremonies. It has been in use for various state occasions, including coronations, since it was built in 1762 for King George III.
The decision to upgrade the Gold State Coach with modern features like electric windows and air conditioning could have several reasons:
Preservation and Maintenance: Historic carriages like the Gold State Coach are valuable artifacts and represent a significant part of a nation's cultural heritage. By upgrading them with modern amenities, it may be possible to better preserve and maintain these historical vehicles for future generations.
Safety and Comfort: The Gold State Coach is used for ceremonial purposes on various state occasions. By adding air conditioning and electric windows, the Royal Family and other occupants can experience improved comfort and safety during processions, especially in warmer weather conditions.
Practicality and Functionality: State occasions often involve elaborate ceremonies and long processions. Upgrading the coach with modern features might make it more practical and efficient for use in contemporary contexts.
Technological Advancements: As technology evolves, it may be possible to integrate modern conveniences into historic carriages without compromising their original appearance and design.
However, it's worth noting that any modifications made to such a historically significant carriage would likely be done carefully and with great consideration for preserving its original charm and historical significance.
