Whoops, no head-up display!

September 2, 2017

In an idle moment recently (I don’t get many of those at the moment) I was scrolling through Honest John’s car advice in the Daily Telegraph. I found this one:

This struck a chord with me, because I’ve just bought a pair of Polarised sunglasses to eliminate reflected glare from the inside of my car windscreen – which can be a major problem if the sun’s in front of me and shining directly onto the top of the dashboard.

So, some basic physics. When light is reflected off a surface, most of the light that’s vibrating parallel to the surface is reflected, while most of the light that’s vibrating at other angles is absorbed or diffused. This means the reflected light is mostly vibrating in one direction – this is what “polarised” light means. Reflections from the inside of a car windscreen will be horizontally polarised.

Polarised glasses are designed to eliminate horizontally polarised light because it’s horizontally polarised light which reflects from surfaces such as roads, puddles and lakes, tables and so on. That’s why I bought my new glasses – to eliminate the reflection from the inside of the windscreen when driving towards the sun.

Head-up displays work by projecting the display upwards so that it reflects off the inside of the windscreen – as shown above.

If you wear Polarised glasses, these will cut out any light reflected from the inside of the windscreen, however it got there, so you will not be able to see a head-up display. Reactolite glasses aren’t polarised, they just darken the lenses, so the display will still be visible.

Obvious really, Honest John!

easyJet Plus card – is it worth it?

October 22, 2015

Short answer: probably not.

If you fly more than 5 round trips (10 sectors) a year on easyJet, AND you book the most expensive allocated seats then it may be worth considering it. Otherwise don’t bother.

How do I know?

Well, I won one.

Yes, I entered a Twitter competition and won a free easyJet Plus card in October 2014. I’ve been using it for a year. It’s now renewal time. My question is – is it worth paying for?

At the time I won one, the price was £149 to join and £139 to renew. However during the year they’ve changed the Speedy Boarding and Plus Card rules, and the price has gone up to £170 per year (£160 if you join on board – but of course if you do that you have at least one flight where you can’t use it). And there’s no discount for renewal.

So in the year since I got the card would I have saved money? I’ve flown 10 sectors in that year, but two were before the card arrived so I couldn’t use it. So 8 sectors. Even if I had chosen the most expensive allocated seat (£15.99) on each flight then the current annual fee for the card significantly exceeds the amount I would have saved.

Surely there are some benefits you don’t get if all you do is pay for seat allocation?

Yes, but only fast track security. Not all airports have one, and we’ve found on at least two occasions that it’s faster at Gatwick (our normal originating airport) to go through regular security rather than Fast Track.

Shame there isn’t a Fast Track arrivals – that would be worth paying for!

But the other benefits: Speedy Boarding, two carry on bags and dedicated bag drop are all available to those who just pay for seat allocation either upfront or in an exit row. Most of mine would have cost £10.99 rather than £15.99, so I’d have had to fly 16 sectors to make it worthwhile – that’s twice as many sectors as I actually flew.

So for me a paid for easyJet Plus card doesn’t work. At the old renewal price of £139 I’d probably just have done it, but at £170 it really doesn’t make economic sense. And since there’s no discount for renewal, if I decide next year that I will be flying enough to make it worthwhile, I’ll simply join again – I can save money by not being a member when I don’t fly – and there’s no penalty for leaving and joining again several months later before your next flight.

Thanks for the freebie easyJet, I really enjoyed it. And I will occasionally miss using the fast track security, but overall it’s just not worth paying for. Sorry.

Sort out passports, UKBA, for the country’s sake

April 28, 2012

The news today is full of reports of 2-hour queues at Heathrow to get passports inspected.

I remember the halcyon days of international travel, back in the 1990s, when getting back into the UK after a trip abroad was a breeze. You stood in line for a few moments with a queue of maybe 10 or 12 people ahead of you. The passport official (now the UK Border Agency of course) took a cursory glance at your passport and you were in.

Back in the halcyon days of travel only getting into the United States was tricky and time consuming. Today getting back into the UK, Read the rest of this entry ?
