30 minutes stuck in traffic would only add £6 between 07:00 and 22:59... 20p per 40 seconds... need to be going very, very slowly for 155.7 yards to take 40 seconds
The thing is, different Councils have different rates, so if you got a Rushmoor licenced cab into Guildford for lunch one Sunday, it would be normal day rate. If you then got a Guildford cab back, it would be double time
When quoting fares, I always used to establish the distance and then approximate the fare from the meter rate,(in our case £4 for the first mile, then £2 for every subsequent mile...) plus 10% so a five mile journey would be quoted at £13.20, but would always meter less. Airport work was different in that people have alot of choice, so you aimed to be competitive not only with your local market, but also with what people were prepared to pay further afield.
As an example, I used to do a regular run from the New Forrest to Solihull and back every Wednesday for £120, which sounds ridiculous, but it meant visting my brother the either before or after, and it typically used the same amount of fuel as hacking around town chasing £4 fares...
When using taxis, do your research and bear in mind the following, in no particular order:
1. The fare card should always be on display. If it isn't, ask to see it. It should have the vehicle id on it too.
2. If prebooking a car, always agree the fare at the time of booking and confirm with the driver. Both amounts should be the same.
3. Most councils allow charges for extra people/bags. It would be a right idiot who actually did so.
4. If the journey is metered, it should always be the shortest distance, not the shortest time. These are not the same thing. Going from Horsham to Gatwick, the quickest route is nearly 8 MILES further. The exception to this rule is in London where the driver chooses the route... Tourists beware. My advice to anyone travelling by taxi within London is this: Always use Addison Lee or Uber as you know that the drivers are correctly licenced and the fare is always set in stone.
5. If you hail or book a cab, and subsequently share it with other people, then you are legally responsible for the whole fare and any extra charges, including soilage. You should ideally be the last person to be dropped off.
6. Soilage charges are typically capped at £100.
7. If a prebooked vehicle offers to take you without a booking, feel free to take the journey and make a note of the car and driver details. When you arrive, get out and walk off. If the driver complains, politely point out that without a booking, they aren't insured and if they're not insured they cannot charge and that perhaps they might be less greedy next time. Obviously don't go to your front door if your playing this game of chess.
8. An out of area Taxi should be treated as a prebooked car, ie you must have booked it to collect you. So a Guildford taxi couldn't legally collect you from Farnborough station without a booking.
9. Ensure that the tariff number on the meter matches that of the card. To use Rushmoors example: At 10:00, on a regular Wednesday the tariff rate on the meter should be 1 and the meter should display £2.70 if there are LESS than five of you.
10. Infants a children DO NOT count as luggage, every passenger should have their own seat. Four adults and one toddler is five passengers, a car licenced for 4 passengers doesn't have enough seats. Yosemite.
That's about it, and a lot of it iscommon sense
